2l+2w=perimeter <= equation for perimeter
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>
<span>and, since </span>
<span>w+4=l <= length is 4 greater than width </span>
<span>then l=4+4 </span>
<span>l=8</span>
Answer:
7; 40
Step-by-step explanation:
No symbol for the term that you are solving for . I will use β
V = βwh Divide by (wh)
V/(wh) = β
β = V/(wh)
β = 735/(21 × 5) = 7
β = 3312/(11.5 ×7.2) = 40
