Hey there! :)

To find out which algebraic expression is equivalent to our given expression, we must simplify everything out.

9(x - 6) + 11(x + 12)

Simplify by using the rainbow method. This just rids us of our parenthesis.

(9 · x) + (9 · -6) + (11 · x) + (11 · 12)

Simplify!

9x + (-54) + 11x + 132

Add like terms.

(9x + 11x) + (-54 + 132)

Simplify.

20x + 78

So, our equivalent equation is C. 20x + 78

~Hope I helped!~

When the points below are connected, they will form triangle ABC. Show and state whether this triangle has a right angle or not.
cluponka [151]

Answer:

See explanartions below

Step-by-step explanation:

Given the coordinates A(-6,3) B(0,5) C(2,-1)

We first need to get the slope of AB, BC and AC

For AB;

A(-6,3) B(0,5)

Mab = 5-3/0-(-6)

Mab = 2/6

Mab = 1/3

For BC;

B(0,5) C(2,-1)

Mbc = -1-5/2-0

Mbc = -6/2

Mc = -3

For AC:

A(-6,3) C(2,-1)

Mac = -1-3/2-(-6)

MAc = -4/8

Mac = -1/2

Taking the product of Mab and Mbc

Mab * Mbc = 1/3 + -3

Mab * Mbc = -1

<em>Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees</em>

Which of the following sets could be the sides of a right triangle?
MArishka [77]
In a right triangle the sum of the squares of the lengths of two shorter sides is equal to the square of the length of the longest side.

a.
2^2+3^2=(\sqrt{13})^2 \\&#10;4+9=13 \\&#10;13=13 \\ true

b.
2^2+2^2=4^2 \\&#10;4+4=16 \\&#10;8=16 \\&#10;not \ true

c.
1^2+(\sqrt{3})^2=2^2 \\&#10;1+3=4 \\&#10;4=4 \\&#10;true

The answer is A and C.

Use the graph to find the x-intercept for the equation y + 2 = 2(x + 3).
Assoli18 [71]

Answer:

The x-intercept is 2

Step-by-step explanation:

So what you would do is you would distribute the 2 to x and 3 to get the equation y+2=2x+6. Then you would subtract 2 from both sides and get y=2x+4. And because your m is your x-intercept you get the answer: 2.
