I think the answer is D. You are doubling (x2) the sum (which is addition, so j+8) so you should have 2(j+8)

Factorise x squared - 12x + 36

slava [35]

Answer:

(x-6)(x-6) or (x-6)^2

Step-by-step explanation:

x^2-12x+36=(x-6)(x-6)

Just find two numbers that when they multiply, you get the third term,

which is 36 in this case. And when they add up, you get the second term,

which is -12 in this case. You can also check the answer by multiplying.

(x-6)(x-6)=x^2-6x-6x+36=x^2-12x+36

Select the equation that has the same solution as the equation below.<br> 5^(2x-5)= 125

Ahat [919]

The equation that has the same solution as $5^{(2x-5)} = 125$ is: C. $64 = 2^{(3x - 6)}$

<h3>How to Solve Equations having Exponents</h3>

To solve such, simplify the bases so that the base on the right equals the base on the left.
Then solve the equation for the variable.

Given:

$5^{(2x-5)} = 125\\\\5^{(2x-5)} = 5^3\\$

The bases will cancel out

2x - 5 = 3

Solve for x

2x = 3 + 5

2x = 8

x = 4

The solution of $5^{(2x-5)} = 125$ is 4.

Thus:

$64 = 2^{(3x - 6)}\\\\2^6 = 2^{(3x - 6)}\\\\6 = 3x - 6\\6 + 6 = 3x\\12 = 3x\\4 = x\\x = 4$

Therefore the equation that has the same solution as $5^{(2x-5)} = 125$ is: C. $64 = 2^{(3x - 6)}$
