Help 50 points and brainlest only if you answer all the questions
klasskru [66]

Answer: See below

Step-by-step explanation:

a) 6(3x+4y-8)

Use the distributive property:

6*3x + 6*4y - 6*8

18x + 24y - 48

<u>So D is the correct answer</u>

b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.

12+4x

= 4(3+x)

<u>So D is the correct answer</u>

c) When you expand both <u>C and D</u> and simplify, you get 16x+36 as solution

d) 14x+2y+10z

Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times

14x+2y+10z

= 2(7x+y+5z)

<u>So D is the correct answer again ;)</u>

Which could be the first step in simplifying this expression? Check all that apply. (x^3x^-6)^2
allsm [11]
If the expression is what I understand it is, this is my answer. (x to the third times x to the negative sixth all squared)

First, i would simplify what is inside the parentheses. x^-6 is the equivalent to
1/x^6. Therefore, the expression inside the parentheses is a fraction: x^3/x^6.

When dividing numbers with exponents, just subtract the exponents. 
3-6= -3     so the simplification of the expression in the parentheses is 1/x^3.

To finish the problem, I would apply the square from outside the parentheses to the values inside them. In this way, the exponent would be multiplied by 2.

Our final answer is 1/x^6.

12. Write the equations in point-slope form of the line that passes through
mario62 [17]

Answer: Y-1=-1/8(X-3)

Step-by-step explanation:

Point slope form is Y-y1=m(x-x1)

the slope here is 2-1/-5-3 = 1-/8

so its Y-1=-1/8(X-3)
