Answer: The expression simplified is 14.9d+3.6h-17.
Step-by-step explanation:
2w + 2l = 25
2 * 2 + 2l = 25
<em><u>Simplfiy.</u></em>
4 + 2l = 25
<em><u>Subtract 4 from both sides.</u></em>
2l = 21
<em><u>Divide both sides by 2.</u></em>
l = 10.5
Now that we have the value of l, we can find the area.
A = lw
A = 10.5 * 2
A = 21.
The length is 10.5cm.
The area of the rectangle is 21cm^2
Answer:
6
Step-by-step explanation:
since their are 3 numbers to choose from we do 3! or 3*2*1 which is 6.
2(2.2)(3.0) + 2(2.2)(7.5) + 2(7.5)(3.0)
13.2 33 45
Theres the work the answer is (4) 91.2
It is 153 meters
9*7 = 63
18*12= 216
216 - 63= 153
