Answer:
≈ 14.6%
Step-by-step explanation:
percentage increase is calculated as
× 100%
increase = 2.75 - 2.40 = 0.35 , then
percentage increase =
× 100% ≈ 14.6% ( to the nearest tenth )
13.2*3.9 =51.48
51.48*6= 308.88
This rounds to 308.9 cm^3
The value of x is x=2.57338 and x=−0.906718
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
3x²-5x-7=0
Using the discriminant method,
a = 3, b = -5, and c = -7
x= -b± √b²-4ac / 2a
x= 5 ± √25 + 84/ 6
x= 5± √ 109
Hence, x=2.57338 and x=−0.906718
