Answer:
The area of square in terms of x = 16x² -24x + 9
Step-by-step explanation:
It is stated in the question that the length of a square = 4x - 3
Formula to find the area of the square is
<h2 /><h2>Area = length²</h2><h2 />
Area = ( 4x - 3 )²
<em>by using ( a - b )² = a² + b² - 2ab</em>
here a = 4x and b = -3
So,
(4x)² + (-3)² - 2(4x)(3)
16x² + 9 - 2(12x)
16x² + 9 - 24x
16x² -24x + 9
The area of square in terms of x = 16x² -24x + 9
Answer:
is it 4.8, I don't really know
Answer:
area is 90 and perimeter is 46
Step-by-step explanation:
the area for a rectangle is l * w, so 18*5 is 90, and the perimeter is 2l+2w, which is 46.
sides 2 * 6 * 4 =48 and 6*4=24
bottom 6*2.5 =15
2.5*4=10
10*2=20 that's the area of 2 smaller sides
Step-by-step explanation:
we add up the dimensions together 48+20+15=83
so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83
