please only give me the right answer I really need it

Answers

Answer 1
Answer:
x = 6, -2

Explanation:
x^2 - 4x - 12 = 0

Answer 2

Answer:

(6, -2)

Step-by-step explanation:

x^2-4x-12=0. 1 from 1x. -4 from -4x

(x - 6)(x + 2) = 0 1 * -12 = -12. -4

x - 6 = 0 -6 * 2 = -12. -6 + 2 = -4

+ 6 +6

- [tex]\frac{3}{8}[/tex] because [tex]\frac{2}{6}= \frac{1}{2} = \frac{2+1}{6+2} = \frac{3}{8}[/tex]

Answer:

- [tex]\frac{3}{9}[/tex] because [tex]\frac{2}{6}= \frac{1}{3}[/tex] and [tex]\frac{1}{3} = \frac{3}{9}[/tex]

Step-by-step explanation:

Two fractions are said to be equal if and only if they give the same value when simplified.

The equivalent of [tex]\frac{2}{6}[/tex] is as explained in the selected option;

First, divide numerator and denominator by 2

[tex]\frac{2/2}{6/2}[/tex]

Then simplify

2/2 = 1 and 6/2 = 3; So;

[tex]\frac{2/2}{6/2} = \frac{1}{3}[/tex]

Multiply numerator and denominator by 3

[tex]\frac{1*3}{3*3} = \frac{3}{9}[/tex]

Hence, [tex]\frac{2}{6}[/tex] is equivalent to [tex]\frac{3}{9}[/tex]

The name of the point is the circumcenter of the triangle

Step-by-step explanation:

The pool will be built at a point which is equidistant from the three points.

This means that the distance from that center point to point A equals the distance from that center point to point B which is equal to the distance from that center point to point C.

The name of this point is called the CIRCUMCENTER of the triangle

The circumcenter is equidistant from the three vertices of the triangle which are the points A , B and C in this case

find the measure of angle 3
please help !!

Answers

Answer:

∠3 = 140°

Step-by-step explanation:

∠4 = 40°

∠4 = ∠1 (vertical angles)

∠1 = ∠2 (alternate angles)

∠2 = 40°

So,

∠2+∠3 = 180 [Angles on a straight line add up to 180°]

40 + ∠3 = 180

∠3 = 180-40

∠3 = 140°

Answer:

Angle 3 = 140°

Step-by-step explanation:

Angle 4 is equal to 40° and on a flat surface of 180°, that is, the first horizontal line, angle A is equal to 140° because 180° - 40° = 140°. Angle A is congruent to angle 3, therefore, angle 3 is also 140°.

Please help. Sooooo confused. GOAL is a quadrilateral in which GO is parallel to AL. If the measures of angle G=angle O = 40 degrees. What are the measures of angle A send L. It is not mentioned that A is equal to L,so?

Answers

Answer:

Angle A and L are 140 degrees each.

Step-by-step explanation:

Since GO and AL are parallel to each other, we can use the same side interior theorem to figure out angle A and L. Let's focus on GA first. We know that same side interior angles are supplementary (sum is 180 degrees). We know angle G is 40 degrees, so to figure out angle A, you do 180-40 which equals 140. So angle A is 140 degrees. You repeat this process for OL and you should also get 140 degrees for L.

You're making dessert but your recipe needs adjustment. Your chocolate chip cookie recipe makes 4 dozen cookies, but you need 3
1
dozen cookies. If the recipe requires 15 cups of butter, 5 teaspoons of baking powder, and 2 cups of pecans, how much of each of
these ingredients are necessary for 3 dozen cookies? Simplify your answer

Answers

Answer:

Butter = (3*15) / 4 = 45/4 = 11 1/4 tsp

Baking powder = (3*5) / 4 = 15/4

= 3 3/4 tsp

Pecans = (3 * 2) / 4 = 6/4

= 3/2 = 1.5 cups

Here, we are required to determine how much of each of these ingredients are necessary for 3 dozen cookies

The ingredients are;

11 and 1 quarter cups of butter is needed.3 and 3 quarters teaspoons of baking powder are needed.1 and a half cups of peacans are needed.

Therefore, for 3 dozen cookies; 3 quarters of the requirements for 4 dozen cookies;

Cups of butter needed = (3/4) × 15 = 11.25

Teaspoons of baking powder needed = (3/4)× 5 = 3.75

Cups of peacans needed = (3/4)× 2 = 1.5

Ultimately,

11 and 1 quarter cups of butter is needed.3 and 3 quarters teaspoons of baking powder are needed.1 and a half cups of peacans are needed.

A geometric sequences is when the previous term is used to find the next. In this case you multiply 10 to the previous term to find the next giving u -5600

Katie went out for dinner with her friends and left a 17% tip. If B represents the bill, an expression that represents the total bill she will pay is 0.83b

Answers

Answer:

Step-by-step explanation:

Katie and her friends will pay 17% of the bill, B.

Therefore, we have to add 17% of B to B to find how much they will pay:

17/100 * B = 0.17B

Therefore, the total bill will be:

Bill + tip

= B + 0.17B = 1.17B

The expression that represents the total bill they will pay is 1.17B

Answer:

£1.31

Step-by-step explanation:

The cakes are sold in the ratio 5 : 7 : 12 = 5x : 7x : 12x ( x is a multiplier )

sum the parts of the ratio, 5x + 7x + 12x = 24x

Equate 24x to the number of cakes sold, that is

24x = 216 ( divide both sides by 24 )

x = 9

Thus cakes sold are

5x = 5 × 9 = 45 small cakes

7x = 7 × 9 = 63 medium cakes

12x = 12 × 9 = 108 large cakes

let p represent the profit on a small cake, then

45p + 63(2p) + 108(3p) = 648.45 , that is

45p + 126p + 324p = 648.45

495p = 648.45 ( divide both sides by 495 )

p = 1.31

That is the profit on one small cake is £1.31

Answers

Answer:

7.385 h

Step-by-step explanation:

In the given expression, "s" is Cecilia's average driving speed in miles per hour, 350 is the distance, in miles, between Atlantic City and Williamsburg, therefore:

For s = 45 mph

[tex]T = 2+\frac{350}{45}\\T=9.778\ h[/tex]

For s = 55 mph

[tex]T = 2+\frac{350}{55}\\T=8.364\ h[/tex]

For s = 65 mph

[tex]T = 2+\frac{350}{65}\\T=7.385\ h[/tex]
