Which expressions are equivalent to -6(b+2)+8−6(b+2)+8minus, 6, left parenthesis, b, plus, 2, right parenthesis, plus, 8 ? Choos

leva [86]

Answer:

B. $-6b-4$

Step-by-step explanation:

Given expression is $-6(b+2)+8$

Simplifying the expression now

Lets use distributive property of multiplication to solve it.

As given, $-6(b+2)+8$

Distributing -6 with b and 2.

= $(-6b-12)+8$

Opening the parenthesis

= $-6b-12+8$

= $-6b-4$

∴ As from the given options, $-6b-4$ is the correct choice.

20 POINTS AND BRAINLIEST!

Advocard [28]

Answer:

<A =21

<B = 84

<c = 75

Step-by-step explanation:

<A =x

<B = 4x

<C =5x-30

The sum of A+B+C = 180

x+ 4x + 5x-30 = 180

Combine like terms

10x -30 = 180

Add 30 to each side

10x-30+30 = 180+30

10x = 210

Divide by 10

10x/10 = 210/10

x= 21

Since x =21 we can find the value of the angles

Substituting x into the equations for angles A, B and C

<A =21

<B = 4x = 4*21 = 84

<C = 5x-30 = 5*21-30 = 105-30 = 75

Infront of the Positive is a one.

-8 +1 (-24)

If we follow order of operations which is parentheses, exponents, multiply divide, add, and subtract, we can see we need to multiply/ distribute first. And a positive times a negative is a negative.

-8 -24

Now we put the two numbers together.

-32

This is the answer
