What is the value of X ?

harkovskaia [24]

The sum of all the angle measures is 180 degrees, now lets set up some equations:

$(3x-35)+(x-35)+x = 180\\5x - 70 = 180\\5x = 110\\x = 22$

Thus x = 22

Hope that helps!

What number is 64 percent of 120?

Viktor [21]

X = 64% of 120

   = 64/100 * 120

   = (64 * 120) / 100

   = 7680 / 100

   = 76.8

The number is 76.8

Which of the following is a root of the polynomial shown below?

Mademuasel [1]

Answer:

We conclude that option A is true as x = 1 is the root of the polynomial.

Step-by-step explanation:

Given the polynomial

$f\left(x\right)\:=\:x^2\:+\:2x^2\:-\:x-2$

Let us determine the root of the polynomial shown below.

$\:0=\:x^2\:+\:2x^2\:-\:x-2$

$0=3x^2-x-2$

switch sides

$3x^2-x-2=0$

$3x^2-x-2=\left(3x+2\right)\left(x-1\right)$

so the equation becomes

$\left(3x+2\right)\left(x-1\right)=0$

Using the zero factor principle

$3x+2=0\quad \mathrm{or}\quad \:x-1=0$

solving

$3x+2=0$

$3x=-2$

$\frac{3x}{3}=\frac{-2}{3}$

$x=-\frac{2}{3}$

and

$x-1=0$

$x=1$

The possible roots of the polynomial will be:

$x=-\frac{2}{3},\:x=1$

Therefore, from the mentioned options, we conclude that option A is true as x = 1 is the root of the polynomial.

An actually director paid $90 for 12 sun visors for the softball team , how much will the athlete director pay to buy 15 more su

Setler79 [48]

112.5$ ..

for the 12 visors if you divide 90 by 12, you get 7.5 which is the total cost of one visor. 7.5(one hat) x 15 visors gives you 112.5 so the total cost will be 202.5
