Answer:
b
Step-by-step explanation:
d = r * t
None of them are really correct, but the closest one is B. Look at the equation. Rate is multiplied by time. The result is distance.
The 90 minutes should be changed to hours. No speedometer on a car is rated in feet per second.
Answer:
D) 2x^2 + 11x^3 + 12x^2 - 10x - 8
Step-by-step explanation:
you multiply each term of the first expression with each term of the second expression and add all the terms
so start with x^2 * 2x^2 = 2x^4
x^2 * 3x = 3x^3
x^2 * -4 = -4x^2
4x * 2x^2 = 8x^3
at this point it's clear that the correct answer is D but we can continue
4x * 3x = 12x^2
4x * -4 = -16x
4x^2
6x
-8
by adding
2x^2 + 11x^3 + 12x^2 - 10x - 8
first you should go left to right when solving these equations:
5/12 ∙ 1/5
= 5/60
Then you multiply 5/60 and 8
5/60 ∙ 8/1 (8/1 is still a whole number. It makes it easier to multiply)
= 40/60 = 2/3
So, the answer is 2/3.
The opposite of 7 on a number line would be -7 because if you look at 0 as a mirror, then the opposite of 7 is -7.
