Hello :
let : x the length and y the <span>width
the perimeter is : 2(x+y)
2(x+y) = 70 and : x/y =4/5
x+y = 35 ......(1)
x = (4/5)y ... (2)
subsct in : (1)
</span> (4/5)y +y = 35
4y+5y = 175
9y = 175
y = 175/9
in (2) : x = (4/5)(175/9) = 140/9
Answer:
c = 6d
Step-by-step explanation:
c = change in y/change in x times days
According to the graph: c = 12/2d
Simplify
c = 6d
The answer is 3/2
Find the slope of the line
M = y2-y1/ x2-x1
M=9-0 /6-0
M=9 divide 3 / 6 divide by 3
M= 3/2 cm/s

Answer:
B. 128 square centimeters
Step-by-step explanation:
So first make the top triangle part its own figure. By using information provided you can figure out the height of the triangle would be 3 by subtracting 11 from 14. Take 3 multiply it by the base and then 1/2 to get 18. Then find the area of the rectangle which would be 10 times 11 which is 110. Add the areas of the two parts, 110 and 18 to get 128.
