Evaluate 4m3-6 for m = 2

26

Step-by-step explanation:

So when solving algebraic equations, it is always important to keep in order of operations.

1.Parenthesis

2.Exponents

3.Multiplication

4.Division

5.Addition

6.Subtraction

In this case, it is exponents first, (m^3)

next multiplication 4(m^3)

and lastly subtraction 4(m^3)-6

now replace m with 2

4(2^3)-6

start over again

2^3 is 8

4(8)-6

32-6=26

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
