Answer: 8.4
Explanation: Substitute y = 0.8 into the equation.
4x + 8(0.8) = 40
4x + 6.4 = 40
4x = 33.6
x = 8.4

=64pi square inches
Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)
= 12 x 57.6 grams
= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams
Answer:
D).
Step-by-step explanation:
ln (e · e^x) = x2 + 4x + 3
ln e^(x+1) = x^2 + 4x + 3
Taking all terms to the power e:
e^(x + 1 )= e^ (x^2 + 4x + 3)
x + 1 = x^2 + 4x + 3
x^2 + 3x + 2 = 0
(x + 2)(x + 1) = 0
x = -2, -1.
