Answer:
3x^3 +14x^2 +2x +35
Step-by-step explanation:
The distributive property is used to find the product of polynomials. Terms can be collected to express the result with terms in order of decreasing degree.
__
(3x^2 -x +7)(x +5)
= x(3x^2 -x +7) +5(3x^2 -x +7) . . . . apply the distributive property
= (3x^3 -x^2 +7x) +(15x^2 -5x +35) . . . . show the products
= 3x^3 +(-1 +15)x^2 +(7 -5)x +35 . . . . . collect like terms
= 3x^3 +14x^2 +2x +35 . . . . . . . . write in standard form
8x-19= -4 - 7x
+4 = -4 - 7x
8x -15= -7x
+7x = -7x
15x - 15=
-15 = 15
15x= 15
x= 1
Answer:
5/10 or 1/2
Step-by-step explanation:
ratio=2:5:3
2+5+3=10 ( total of counters)
10=denominator
blue = ratio 5
5/10
or 1/2 simplified
Answer:
option: A and Option: B are correct.
Step-by-step explanation:
We are given a scatter plot we are asked to find which of the given statements hold true such that it's ranges describe the cluster in the scatter plot.
Clearly from the scatter plot we could see that:
The most of the points are between 6-12 years of experience in the scatter plot.
also the earnings are between $40,000 and $60,000 that covers most of the data.
Hence, option A. ( A. between 6 and 12 years of experience) and Option B ( B.
between $40,000 and $60,000 ) are correct.
