31.4/3.14=10
10/2=5
5*5*3.14= 78.5 cm square
Answer:
-4.5
Step-by-step explanation:
15(2-x)=13(3-x)
Expand parentheses:
30-15x=39-13x
Add 15x to both sides:
30=2x+39
Subtract 39 from both sides:
2x=-9
Divide both sides by 2:
x=-4.5
Hope this helps!
P=2L+2W
80=2*26+2W
so then you could find the missing number of W which is
W=14
Thank you so much, you too.
