Answer:
The answer is C=6p3 + 29p2 + 22p – 21
Step-by-step explanation:
To calculate the product, we need to multiply each member of each multiplier:
(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3
= 6p³ + 8p² - 6p + 21p² + 28p - 21
= 6p³ + 8p² + 21p² + 28p - 6p -21
= 6p³ + 29p² + 22p - 21
Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21
Answer:
C. $412.50
Step-by-step explanation:
We can use proportion:
12 meals --- 3 pounds
250 meals --- x pounds
x=(250 meals*3 pounds)/12 meals = 62.5 pounds
62.5 pound * $ 6.60/pound = $ 412.50
Having a fraction as a factor in a multiplication is operated by multiplying the numerator by any whole number and leaving alone the denominator, or if you multiply fractions, then you multiply numerators and denominators separately.
So in this case you have 8 halved apples, that is, 8 times one half apples:
8*(1/2)
this we solve by multiplying the whole number 8 times the numerator 1, and dividing by the denominator:
= 8*1/2
= 8/2
so you have 8 halved apples, which means
= 4
4 apples
Answer:
20
Step-by-step explanation:
if its one fifth than we can just multiply by 5
4 x 5 = 20
hope this helps : )
Ten times (10 x) the sum (+) of half a number (
) and 6 (6) is 8 (=8)
10(<span>
+ 6) = 8 Use the Distributive Property
</span>
+ 60 = 8 Simplify the fraction
<span> 5n + 60 = 8 Subtract 60 from both sides
5n = -52 Divide both sides by 5
n = -10</span>
