Step-by-step explanation:
Answer:
22a + 3c
Step-by-step explanation:
Let's simplify step-by-step.
5(2a−c)+4(3a+2c)
Distribute:
=(5)(2a)+(5)(−c)+(4)(3a)+(4)(2c)
=10a+−5c+12a+8c
Combine Like Terms:
=10a+−5c+12a+8c
=(10a+12a)+(−5c+8c)
=22a+3c

A rectangular pyramid has a volume of 32 cubic feet. Find one possible set of measurements
for the base area and height of the pyramid.
Answers
Answer:
Ghe possible set of measurements for the base area and height are;
(96, 1)
(48, 2)
(32, 3)
(24, 4)
(16, 6)
(12, 8)
Step-by-step explanation:
Formula for volume of a rectangular pyramid is;
V = ⅓Bh
Where;
B is area of base
h is height of pyramid
Thus, if volume is 32, then;
32 = ⅓Bh
Multiply both sides by 3 to get;
Bh = 96
Factors of 96 are; 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96
Thus, the possible set of measurements for the base area and height are;
(96, 1)
(48, 2)
(32, 3)
(24, 4)
(16, 6)
(12, 8)
Rita makes strawberry jam every year. The number of quarts of jam she makes this year can be represented by the expression 3q - 8, where q is the number of quarts of jam she made last year. Rita made 10 quarts last year. How many quarts does she make this year? Help pleaseeee it’s urgent
Answers
Answer:
22 quarts
Step-by-step explanation:
3(10)-8
= 22
We will subsitute the q for 10, since in the expression it says she made 10 quarts last year.
Our new expression is 3(10)-8=
22 quarts

Use the Rational Root theorem to determine the factors of x^3 - 2x^2 - 13x - 10 given that one factor is (x + 1)
Answers
Answer:
The correct option is;
D. (x - 5)·(x + 2)·(x + 1)
Step-by-step explanation:
The Rational Root theorem is expressed mathematically as follows;
[tex]Possible \ rational \ roots = \dfrac{Factors \ of \ the \ constant \ term}{Factors \ of \ the \ leading \ coefficient}[/tex]
The given polynomial is presented as follows;
x³ - 2·x² - 13·x - 10
A factor of the polynomial = (x + 1)
The factors of the constant term, -10 = -10, -5, -2, -1, 10, 5, 2, and 1
The factors of the leading coefficient, (the coefficient of the variable having the highest degree or power, x³) = 1
Given that (x + 1) is a known factor, the other two factors are either (x + 5) and (x - 2) or (x - 5) and (x + 2)
The option, that combines (x + 1) and the other two factor combination is (x - 5)·(x + 2)·(x + 1)
∴ The solution which meets the condition is (x - 5)·(x + 2)·(x + 1)
We check;
(x - 5)·(x + 2)·(x + 1) = x³ - 2·x² - 13·x - 10

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a blue marble is
5/12
.
There are 72 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Answers
Answer:
42 reds.
Step-by-step explanation:
There are 72 marbles in the bag.
P(Red) = 1 - Blue = 1 - 5/12 = 7/12
P(red) = 7/12 * 72 = 42
If 1 - 5/12 confuses you, then find the blue first
5/12 * 72 = 5 * 72/12 = 5 * 6 = 30
The rest must be red.
72 - 30 = 42
