Answer:
w=14
l=18
Step-by-step explanation:
To find the dimensions, create an equation for its area and solve for each using the area formula A = l*w. The dimensions given are A = 252, w for width and l= w+4 (4 more than the width).
![A = l*w\\252 = (w+4)*w\\252 = w^2+4w\\252+4 = w^2 +4w +4\\256 = (w+2)^2\\\sqrt{256} =\sqrt{(w+2)^2} \\16 = w+2\\16 = w+2\\14= w\\](https://tex.z-dn.net/?f=A%20%3D%20l%2Aw%5C%5C252%20%3D%20%28w%2B4%29%2Aw%5C%5C252%20%3D%20w%5E2%2B4w%5C%5C252%2B4%20%3D%20w%5E2%20%2B4w%20%2B4%5C%5C256%20%3D%20%28w%2B2%29%5E2%5C%5C%5Csqrt%7B256%7D%20%3D%5Csqrt%7B%28w%2B2%29%5E2%7D%20%5C%5C16%20%3D%20w%2B2%5C%5C16%20%3D%20w%2B2%5C%5C14%3D%20w%5C%5C)
The width is 14 so the length is l=w+4 or l= (14)+4 =18
Answer:
$20.39
Step-by-step explanation
42.7 divided by 11.1 is 3.85
Now we multiply that by 5.30
And we get 20.39
When f(x) is substituted with a number, you just plug the number into wherever you see x:
_____________
f(12) = 3/2x + 14
f(12) = 3/2(12) + 14
f(12) = 18 + 14
f(12) = 32
f(-4) = 3/2x + 14
f(-4) = 3/2(-4) + 14
f(-4) = -6 + 14
f(-4) = 8
f(0) = 3/2(0) + 14
f(0) = 0 + 14
f(0) = 14
