Answer 1

Answer:

2x² + 15x + 27

Step-by-step explanation:

(2x + 9)(x+3)

2x² + 6x + 9x+ 27

2x² + 15x + 27

Answer 2

Answer:

2x² + 15x +27

Step-by-step explanation:

Using FOIL:

⇒ 2x * x = 2x²

⇒ 2x * 3 = 6x

⇒ 9 * x = 9x

⇒ 9 * 3 = 27

It would add up to; 2x² + (6x + 9x) +27 and simplifying the parenthesis would simplify to 2x² + 15x +27.

Answer:

Step-by-step explanation:

x^3+7x^2+5x^2+35x

= x^3+12x^2+35x

Answer:

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:

4x = 8 + 3y
x − 2y = −3

What was the temperature of City A and City B on that day?

City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.

Answers

Answer:

City A was 5 and city B was 4

Step-by-step explanation:

Use substitution. Move 2y over so you have x=-3+2y

Plug that into 4x=8+3y

4(-3+2y)=8+3y

-12+8y=8+3y

subtract 3y from both sides

add 12 to both sides

5y=20

20 divided by 5

y=4

then youd plug it into the other equation

x-2(4)=-3

x-8=-3

x=5

therefore the answer is A

p - 0.27p = $ 219

0.73p = $ 219

p = $ 219 / 0.73

p = $ 300. i don't know if this is fully right tho

Answer: 409.23

Step-by-step explanation:  Step 1: If 65% of a number is 266, then what is 100% of that number? Setup the equation.

266

65% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

65Y = 266 x 100

65Y = 26600

Y = 26600

100 = 409.23

Answers

Answer:

Brainliest please

Step-by-step explanation:

Simplifying

3x + -1s = r

Reorder the terms:

-1s + 3x = r

Solving

-1s + 3x = r

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-1s + 3x + -3x = r + -3x

Combine like terms: 3x + -3x = 0

-1s + 0 = r + -3x

-1s = r + -3x

Divide each side by '-1'.

s = -1r + 3x

Simplifying

s = -1r + 3x
