Select all equations that are equivalent to x2+6x=16.
Answer:
The third one and the last one:
x²+6x+9=25
(x+3)²=25
Step-by-step explanation:
If you need an explanation tell me in comments <3
(x + 3)² = 25 and x² + 6x + 9 = 25 are equivalent to x² + 6x = 16.
What is a quadratic equation?
A quadratic equation is an algebraic equation of 2nd degree usually in the form of ax² + bx + c = 0.
Given,
x² + 6x = 16
⇒ x² + 2 × 3 × x = 16
⇒ x² + 2 × 3 × x +9 = 16 + 9
⇒ (x)² + 2 × 3 × x +9 = 25
⇒ (x + 3)² = 25
⇒ x² + 6x + 9 = 25
Hence, (x + 3)² = 25 and x² + 6x + 9 = 25 are equivalent to x² + 6x = 16.

Directions: Find the surface area of each figure.
1.
20.7 in
4
11 in
11 in
Answer:
576.4 in²
Step-by-step explanation:
Surface area of square pyramid = Base Area + ½(perimeter of base)(slant height)
Base area = s² = 11² = 121 in.²
Perimeter of base = 4(11) = 44 in.
Slant height = 20.7 in.
Plug in the values
Surface area = 121 + ½(44)(20.7)
= 576.4 in²

Answer:
[tex]\boxed {\boxed {\sf 8}}[/tex]
Step-by-step explanation:
This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs of the triangle and c is the hypotenuse.
In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:
[tex]a= 7 \\b= \sqrt{15}[/tex]
Substitute these values into the formula.
[tex](7)^2+(\sqrt{15})^2=c^2[/tex]
Solve the exponents.
(7)²= 7*7=49[tex]49+ (\sqrt{15})^2=c^2[/tex]
(√15)²=√15*√15=15[tex]49+15=c^2[/tex]
Add.
[tex]64=c^2[/tex]
Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.
[tex]\sqrt{64}=\sqrt{c^2} \\\sqrt{64}= c\\8=c[/tex]

X (x – 5)² = x² – 52
= x2 - 25
Answer:
Answer:
x=−1.27794
Step-by-step explanation:
x(x−5)2=x2−52
x3−10x2+25x=x2−52
Step 1: Subtract x^2-52 from both sides.
x3−10x2+25x−(x2−52)=x2−52−(x2−52)
x3−11x2+25x+52=0
Step 2: Use cubic formula.
x=−1.27794

Answer:
a) 11.283 dollars
b) 1.435 hour
Step-by-step explanation:
1 kilo watt of electricity used for 1 hour
Charges of electricity per unit = $0.05224
Laura uses 5 heaters to warm her house. The electricity consumed by each use 1800 wats or 1.8 kilo wats
a) Charges in one day = 5 heaters * 1.8 kilo wats per hour * 24 hour* $0.05224 per kilowats per hour
= 11.283 dollars
b) 75 wat light bulb consumes 0.075 kilo wats per hour
Charge per kilowat per hour = $0.05224
In order to cost 1 $, the 75 wat bulb need to be on for 1.435 hour
Carter invested $16,000 in an account paying an interest rate of 5.6% compounded monthly. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $29,600?
Answer:
11 years.
Step-by-step explanation:
Given that Carter invested $ 16,000 in an account paying an interest rate of 5.6% compounded monthly, to determine, assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $ 29,600, the following calculation must be performed:
16,000 x (1 + 0.056 / 12) ^ Yx12 = 29,600
Y = 11
16,000 x 1.4666 ^ 132 = X
29,581.70 = X
Thus, rounded to the nearest year, it would take 11 years for the account to reach $ 29,600.
