3y×(2y+5)

Multiply each term in the parentheses by 3y

3y×2y+3y×5

Calculate the product

6y²+3y×5

Now we do the same thing only different way

3y×2y

Multiply the numbers

6y×y

If a term doesn't have an exponent , it is considered that the exponent is 1

6y^1×y^1

Multiply the terms with the same base by adding their exponents

6y^1+1

add the numbers

6y²

6y^2+3y×5×

calculate the product

6y²+15y

It's the same thing only different way ok

3y×5

Multiply the numbers

15y

answer: 6y²+15y

Which of the following best describes the parallelograms shown below?

Nesterboy [21]

Answer:

The statement "Parallelogram 1 and parallelogram 2 are similar because parallelogram 2 can be created by rotating, reflecting, translating and dilating parallelogram 1" is correct.

Step-by-step explanation:

This statement is correct because the two shapes cannot be congruent; parallelogram 2 is a different size than parallelogram 1. They must be similar, and the third statement is the only statement with a dilation.

Given the system of equations, what is the solution?

Elena L [17]

Answer:

{(-34/7, -16/7)}

Step-by-step explanation:

Rearrange values, multiply to solve for x.

(5) 2y = 3x + 10

(-2) 5y = 4x + 8

Solve for x.

10y = 15x + 50 ↓

-10y = -8x -16

Combine and evaluate.

0 = 7x + 34

Subtract 34 from both sides.

7x = -34

Divide both sides by 7.

x = $\frac{-34}{7}$

Plugin x value into either equation to solve for y.

2y = (3 × $\frac{-34}{7}$ ) + 10

2y = $\frac{-102}{7}$ + 10

2y = $\frac{-32}{7}$

y = $\frac{-16}{7}$

If x = 10, y = 5, and z = 11, what is the tangent ratio for g°?

loris [4]

Please, find attached the image with the complete question

Answer:

$\large\boxed{\large\boxed{tan(g\º )=2}}$

Explanation:

The triangle ACB is a right triangle with these features:

x represents the opposite side to the angle g

y represents the adjacent side to the angle g

The <em>tangent ratio </em>on an angle in a right triangle is equal to the length of the leg opposite to the angle divided by the length of the leg adjacent to the angle.

Hence:

$tangent(g\º )=x/y=10/5=2\leftarrow answer$
