Answer:

3z^2 + 4z+1

Step-by-step explanation:

(3z + 1)(z + 1)

we multiply it to get the polynomial

Apply FOIL method to multiply

Multiply 3z with z+1 first

3z *z = 3z^2

3z * 1 = 3z

Now multiply 1 with z+1

1*z= 1z

1*1= 1

Now we write all the terms together

3z^2 + 3z +1z +1

Combine like terms

3z^2 + 4z+1

Answer:

4 + 9x² + 1x³ + 12x⁵

Step-by-step explanation:

3x² + 6x² = (3 + 6)x² = 9x²

4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵

                                                    = 4 + 9x² + 1x³ + 12x⁵

A man traveled 24 miles in 20 minutes and 18 miles in 15 minutes. Assume that the distance varies linearly with time. How far wi
Norma-Jean [14]

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles

n = 2/3 x 5/4    . . . . .. if fraction is moved to other side of the equation the numerator and denominator will be swithced

n = 10/12     ......................... divide numerator and denominator by 2

n = 5/6
