Answer:
Step-by-step explanation:
We know that the length is four times the width, so:
We also know the area, which is 324 m². The formula for area:
Insert the known values:
Solve for w. Simplify by removing parentheses:
Divide 4 from both sides to isolate the variable:
Find the square root of both sides:
The width is 9 m.
We know the width. Now find the length by using the area formula and inserting known values:
Solve for l. Divide both sides by 9:
The length of the rectangle is 36. (You can check: 4 times 9 is 36)
Now find the perimeter:
Insert values:
The perimeter is 90 m.
5∛x + 4 = 44
5∛x = 40
∛x = 8
x = 8^3
x = 512
answer
C. 512
Answer:
The total cost y of a meal.....
Step-by-step explanation:
The total cost of the meal Y suggests addition, which if you added the x and w portions, you would end up with y.
The other answers suggest subtraction, division, or multiplication, which is not being illustrated by the model.
Answer:
h=6
Step-by-step explanation:
a=b x h x 0.5
9=3 x h x 0.5
9/3=3/.5=6
