Answer:
WRONG THE ANSWER IS ACUALLY C
Step-by-step explanation:
I know this because i decided to take th4e test use his answer and it was wrong telling me the right answer it's (c).
Your answer is B. 2
This is because to rationalise the denominator, we need to multiply it by (3 - √7), so we get:
(3 + √7)(3 - √7)
3 × 3 = 9
3 × √7 = 3√7
3 × -√7 = -3√7
√7 × -√7 = -7
So all in all you get 9 - 7 which is 2.
I hope this helps!

Step-by-step explanation:
so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.
Equation:
(x+3x-4)*2=72
(4x-4)*2=72
8x-8=72
8x=80
x=10
length:10
width:26
Answer:
X = -8
