Answer:
1.No- that just means that the numbers on that side are smaller
Step-by-step explanation:
15 because 3/4 is equivalent to 75% and 75% of 20 is 15.
Answer: equation
Reasoning: So an easy way to remember this is, an equation has an equals sign. So remember equal sounds like equation so that’s a way to know. And an expression doesn’t have an equals sign.
f(x) = 5x − 1 and g(x) = 2x^2 + 1
(f × g)(x) = (5x − 1)(2x^2 + 1)
(f × g)(x) = 10x^3 - 2x^2 + 5x - 1
Substitute x = - 3
(f × g)(-3) = 10(-3)^3 - 2(-3)^2 + 5(-3) - 1
(f × g)(-3) = 10(-27) - 2(9) -15 - 1
(f × g)(-3) =-270 - 18 - 16
(f × g)(-3) = -236
Answer
- 236
