Find the missing angle of a triangle with 60 degrees and 40 degrees

1 answer:

3 0

The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.

60 + 40 + ? = 180

100 + ? = 180

? = 80

The missing angle in the triangle is 80 degrees.

Hope this helps!

Create a factorable polynomial with a GCF of 7. Rewrite that polynomial in two other equivalent forms. Explain how each form was

Aleks [24]

This looks like an odd problem.
Just start with a simple expression with 7 as a factor, and then multiply it out.
For example:
7(x+1)(x+2)
Here 7 could be the GCF.
Now multiply it out:
7(x^2+3x+2) =
7x^2+21x+14
So our factorable polynomial is 7x^2+21x+14
And its two equivalent forms are:
7(x^2+3x+2)and7(x+1)(x+2)

3(2x+1) =9 Show work please

Sladkaya [172]

Answer:

x=1

Step-by-step explanation:

Given

3(2x+1)=9

Distribute left side

3(2x+1)=9

3(2x)+3(1)=9

6x+3=9

Subtract 3 on both sides

6x+3=9

6x+3-3=9-3

6x=6

Divide both sides by 6 to isolate "x"

6x=6

6x/6=6/6

x=1

Final answer

x=1
