Answer:
C). 54 cm.
Step-by-step explanation:
I think you mean a rectangle .
If the length is x then the width = 0.75x (because 3/4 = 0.75).
Perimeter = 2*length + 2*width.
252 = 2x + 2*0.75x
252 = 2x + 1.5x
252 = 3.5x
x = 252 / 3.5
= 72 which is the length,
The width = 3/4 * 72
= 54 cm.
8/14 cause 4+4 is 8 7+7 14
Answer:
2x^2-29 its A
Step-by-step explanation:
5x-5=-25
2x-2=-4
-25+-4=-29
X x X=x^2
X^2 + X^2=2x^2
Hi !

We need to prove that it is equal to

As per given options, Substitute <em>u</em> by <em>t</em><em>+</em><em>1</em><em> </em>

<em>Then</em><em> </em><em>given</em><em> </em><em>t</em><em> </em><em>=</em><em> </em><em>u</em><em>-</em><em>1</em>

Then substitue the third given value also

Therefore, it's <u>proved</u>
