Answer:
13.6
Step-by-step explanation:
If the total area of the painting and the frame is 58 sq ft, we have the equation:
(8 + 2x)(7 + 2x) = 58
Expanding the equation,
56 + 30x + 4x^2 = 58
Combining like terms and arranging the equation, we have:
4x^2 + 30x - 2 = 0
Therefore, the answer is
C. 4x2 + 30x − 2 = 0
Percent formula : is/of = %/100
what percent of 60 is 15....
is = 15
of = 60
% = x
now we sub
15/60 = x/100
cross multiply
(60)(x) = (15)(100)
60x = 1500
x = 1500/60
x = 25
so 25% of 60 is 15
