Use the Distributive Property to simplify the expression.<br> 8(5g+5−2)=
Vaselesa [24]
You multiply the number 8 to each term in the parentheses. 8 x 5g = 40g; 8 x 5 = 40; 8 x (-2) = -16 Combine these together and it would be 40g + 40 - 16

The formula
Tasya [4]

Answer

the answer is P=7.8

Step-by-step explanation:

P=14.7e           -0.21x

X=14.7e      (-0.63)

take the natrual log of both sides

1n(P)=1n(14.7e(-.63)

1n(P)=1n(14.7)-.63

(because ln(e^a) = a)

1n(P)=2.688 - .63

1n(P)=2.058

P=e       2.058

P=7.8
