solve by factorising x² + 11x + 30 = 0
dont get think one could someone explain this please.
Answer:
x={-5,-6}
Step-by-step explanation:
x²+11x+30=0
x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)
x(x+5)+6(x+5)=0
(x+5)(x+6)=0
so
x+5=0
x+6=0
therefore
x=-5
x=-6
Answer:
x = - 6, x = - 5
Step-by-step explanation:
Given
x² + 11x + 30 = 0
Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (+ 11)
The factors are + 6 and + 5 , since
6 × 5 = 30 and 6 + 5 = 11, then
x² + 11x + 30 = 0
(x + 6)(x + 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x + 5 = 0 ⇒ x = - 5
Last year George sold $82 worth of vanishing potion. This year he sold $118 of it. What percent of last year's sales is this year's sales?
Answer:
70%
Step-by-step explanation:
Given data
Last years worth of vanishing potion= $82
This years worth of vanishing portion= $118
Note: Another way of asking this question is "what percent of $82 is $118"
So
=82/118*100
=0.69*100
=69%
=70% approx
Hence last years sale is 70% of this year's sales

Answer:
x = 7.5
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{9}{x}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )
6x = 45 ( divide both sides by 6 )
x = 7.5
Solve for x: x — 10 = 3х – 12
Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x−10−3x=3x−12−3x
−2x−10=−12
Step 2: Add 10 to both sides.
−2x−10+10=−12+10
−2x=−2
Step 3: Divide both sides by -2.
−2x/−2 = −2/−2
x = 1
solve for x
4х + 2 = 3х - 7

Answer:
The correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by [tex]\pi[/tex]
Option D is correct option.
Step-by-step explanation:
The circumference of table top = 24 [tex]\pi[/tex] inches
We need to find area of table top
The formula used to find area is: [tex]Area = \pi r^2[/tex]
We need to find radius of tabletop.
The formula used to find circumference is: [tex]Circumference = 2\pi r[/tex]
Putting value of circumference we can find radius
[tex]Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12[/tex]
So, radius of table top = 12
Now, finding the area:
[tex]Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2[/tex]
So, the correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by [tex]\pi[/tex]
Option D is correct option.

You start at (-1, 2). You move right 5 units and down 6 units. Where do you end?
Answer:
(4,-4)
Step-by-step explanation:
Just plot it or like I did it like this
Since moving right or left is X axis, just add 5 to -1 becuase its ont he X axis
Then for the bottom and up, thats Y so subtract that to the Y axis so 2-6=-4
4,-4

Answer:

Step-by-step explanation:
Emma is playing miniature golf. Her ball is 2 feet of the right-wall. The hole is 4 feet to the left of the wall. The distance along the wall between her ballet and the hole is 18 feet. There is an obstacle between between her ball and the hole, so Emma must hit her ball off the right-hand wall to reflect it towards the hole. How far down the wall should she aim?
Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.

Find the value of c. Give the answer in simplest radical form.
Answer:
x = 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + (2[tex]\sqrt{2}[/tex] )² = 4²
x² + 8 = 16 ( subtract 8 from both sides )
x² = 8 ( take the square root of both sides )
x = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

Answer:
We conclude that the gradient of the line is: 2/3
Step-by-step explanation:
It is clear that the given graph represents a line or linear function.
From the graph, taking two points
(3, 0)(0, -2)Finding the gradient or slope of the line
Using the formula
Gradient = m = [y₂ - y₁] / [x₂ - x₁]
= [-2 - 0] / [0 - 3]
= -2 / -3
= 2/3
Thus, the slope of the line = m = 2/3
Therefore, we conclude that the gradient of the line is: 2/3
