c = (</span>a - 7b - 9d + 10) / 8
Answer:Where is the graph?
Step-by-step explanation:
Well first you find the area of your basic rectangle with equation:
area (a) = length (L) * width (w)
So we got:
a = L * w
Now we find the area of a new rectangle with quadruple side lengths than our (a) rectangle and im going to call this area A:
A = 4L * 4w or A = 4 (L * w)
we want to see how the ratio of A to a or A/a so we can set both equations equal to 1 by dividing the areas to both sides of their respective equations:
1 = (L * w) / a and
1= 4(L * w) / A
since they both equal 1 then the equations have to equal each other:
(L * w) / a = [4 (L * w) / A
cross multiply
A *(L * w) = a *[4 (L * w)]
divide both sides by (L * w)
A = 4a
as you can see by quadrupling the sides by 4, this small rectangles area would also increase by a factor of four
Answer:
100 inches
Step-by-step explanation:
Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .
<u>Using</u><u> </u><u>this </u><u>concept</u><u> </u><u>,</u><u> </u>
=> AM / PN = QA / QP
=> 108 / 71 = 52 + x / x
=> 1.52 x = 52 + x
=> 1.52 x - x = 52
=> 0.52 x = 52
=> x = 52/0.52
=> x = 100 in .
