$x = 4$

$ac = 56$

Step-by-step explanation:

$6x + 3 = 7x - 1$

$7x - 6x = 3+ 1$

$6x + 3 + 7x + 1 = 56$

$x = 4$

In the xy-plane, the graph of function f(x) has zeros at −5, −2, and 2. Write the polynomial function.

Answer:

$f(x) = x^3 +5x^2-4x-20$

Step-by-step explanation:

Given

$Zeros: -5,-2,2$

Required

The polynomial function

If a function has a, b and c as its zeros, the function is:

$f(x) = (x - a)(x - b)(x - c)$

So, we have:

$Zeros: -5,-2,2$

$f(x) = (x - (-5))(x - (-2))(x - 2)$

Open the inner brackets

$f(x) = (x +5)(x +2)(x - 2)$

Expand the difference of two squares

$f(x) = (x +5)(x^2 - 4)$

Expand

$f(x) = x^3 +5x^2-4x-20$

A tree house costs $530. You plan to save $10 each week. Your parents will help pay $80 of the cost. Your savings plan can be mo

ivanzaharov [21]

The answer would be 45 weeks, since you do 530-80 since that is the part the parents will foot, which will be 450 left. Then you do that divided by 10 since you plan to save 10 dollars a week and therefore are left with 45 weeks.

Two lines are intersecting. What is the value of x? Enter your answer in the box. (x + 23) (2x + 4)° Help! Please!!!

Delicious77 [7]

Answer:

$x = 51^o$

Step-by-step explanation:

Given

Intersecting lines

Required

Find x

To do this, we make use of:

$x + 23^o + 2x + 4^o = 180^o$ --- angle on a straight line

Collect like terms

$x + 2x = 180^o - 4^o - 23^o$

$3x = 153^o$

Divide both sides by 3

$x = 51^o$
