An actor gained 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story describ

Tom [10]

We are given statement " gained 20 pounds and loses 15 pounds".

Note: We take plus or positive sign for gain word and we take minus or negative sign for the loses word.

Gained 20 means +20.

Loses 15 mean -15.

Therefore, we can setup an expression as:

20 is a positive number and 15 is a negative number.

Because we have opposite signs of numbers, we would subtract them.

20-15 = 5 pounds.

A right triangle is given with a missing value of t. It is stated that the triangle is an acute right triangle with angles 50∘ a

sergiy2304 [10]

Answer: t=20°

Step-by-step explanation:

1. By definition, the sum of the interior angles is 180 degrees.

2. Keeping the information above on mind, you can write the following expression:

$90+50+2t=180$

3. Now, you must solve for $t$ as following:

$140+2t=180\\2t=180-140\\2t=40\\t=\frac{40}{2}\\t=20$

4. Therefore, the value of $t$ is 20°

What are the x-intercepts of y=2x^2+6x-20?

NISA [10]

Answer:

the x-intercepts are -5 and 2

Step-by-step explanation:

$y=2x^2+6x-20$

x-intercept is when y is set equal to zero

So, y = 0

$0 = 2x^2+6x-20$

$2x^3+6x-20 = 0\\Taking \ 2 \ common\\2(x^2+3x-10) = 0\\Dividing \ both \ sides \ by \ 2\\x^2+3x-10 = 0\\Using \ mid\ term \ break \ formula\\x^2+5x-2x-10 = 0\\x(x+5)-2(x+5)=0\\Taking \ (x+5) \ common\\(x+5)(x-2) = 0$

Either,

x+5 = 0 OR x-2 = 0

x = -5 OR x = 2

So, the x-intercepts are -5 and 2
