Answer:

4x + 4y - 8

Step-by-step explanation:

Step 1: Distributive Property

Distributive property says you would multiple all the terms inside the bracket by the coefficent infront of the bracket

Step 2: Solve

$4x-8+4y\\4x+4y-8$

Step 3: Therefore Statement

Therefore 4(x - 2 + y) simplifies into 4x + 4y - 8

Write in simplest radical form: √7/8 Show all work

ratelena [41]

√7/8

= √7 / √8

= (√7 * √8) / (√8 * √8)

= (√7 * √(2^2 * 2) / 8

= 2√14 / 8

= √14 / 4

For the following problem, match the name of the number property that was used to get to each step from the previous step.

madam [21]

Answer:

1) Given, 2) Inverse property of addition, 3) Commutative property/Identity property of addition, 4) Inverse property of multiplication, 5) Identity property of multiplication/Result.

Step-by-step explanation:

In this exercise we present what real number properties are used in each step of the given procedure with its respective explanations:

1) $37\cdot 2\cdot \left[(-5)+5+\frac{1}{2} \right]$ Given

2) $37\cdot 2\cdot \left(0+\frac{1}{2} \right)$ Inverse property of addition

The inverse property of addition states that:

$u + v = 0$ , $\forall \,u, v \in \mathbb{R}$

$v = -u$

3) $37\cdot 2 \cdot \left(\frac{1}{2} \right)$ Commutative property/Identity property of addition

The commutative property of real numbers states that:

$u+v = v+u$ , $\forall \,u,v\in\mathbb{R}$

The identity property of addition of real numbers states that:

$u+ 0 = u$ , $\forall \,u\in\mathbb{R}$

4) $37\cdot 1$ Inverse property of multiplication.

The inverse property of real numbers states that:

$u\cdot v = 1$ , $\forall\,u,v \in \mathbb{R}$

$v = u^{-1} = \frac{1}{u}$

5) $37$ Identity property of multiplication/Result.

The identity property of multiplication of real numbers states that:

$u\cdot 1 = u$ , $\forall \,u\in \mathbb{R}$

7. Determine the measures of the two angles that are not 90° in the diagram below. Show your

nekit [7.7K]

First we need to assume that the sum of the angles is also 180°. if one is less than 90°, the other will be more. we can do this because in a plane 4-sided polygon the sum of the inner angles will always be 360°, and we already know the two angles on the right side

so we can say that:

3x + 20 + x = 180

Since we got only one variable in this equation, we can already solve for x.

4x + 20 = 180

4x = 160

x = 40

the lower left angle is just 40°

the upper left is three times that plus 20, so it's 160°

hope this helps you to get the method
