P = 4x + 2(x + 5)
That’s the expression
P = perimeter
You could use simple factoring to solve this. You would factor out a 7 and then have
7(3+4m) = A
l x w = A
w= 3 +4m
Answer:
21%
Step-by-step explanation:
3*7/42*3=21/100=21%
The volume of the rectangular prism is equal to length times width times height. Since length and width are equal, the formula includes the squaring of the length. after substitution, the formula is 9^2 * 5 equal to 405 m^3.
So the answer is D. 405 cubic meters
$180
Step-by-step explanation:
<em>Just calculate the perimeter.</em><em>.</em><em>.</em>
4 yards = 12 feet
<em>And add everything up-</em>
18+10+(18-10)+12+12
=60 feet
60 x 3 =<u>180</u>
<em>There you go</em>
