6. Find the perimeter of the figure below
liraira [26]

Answer:

26 in.

Step-by-step explanation:

» <u>Concepts</u>

The perimeter for a shape is the total distance around it measured in units. The formula to find the perimeter of a trapezoid is a + b + c + d, where a & b are the bases, and c & d are the lengths of the other sides.

» <u>Solution</u>

Adding up all the sides, we get:

  • 11+7+4+4
  • 18+4+4
  • 22+4
  • 26

26 inches

Hello there!
Goryan [66]

(x^2+3)^2 + 7x^2+21=-10

We want to convert this equation in terms of m, where m = x^2+3

While solving this problem, I instantly noticed the x^2+3 in the first term of the equation. Replace that with m.

m^2 + 7x^2+21=-10

Simplifying the rest is not as obvious. Using the distributive property, we can change [7x^2+21] to [7(x^2+3)]

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to m^2 + 7m=-10 and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D

Which of the following is a polynomial with roots 4, -5, and 7?
o-na [289]

Answer:

A

Step-by-step explanation:

given the roots of a polynomial, say x = a, x = b and x = c, then

(x - a), (x - b) and (x - c)  are it's factors and the polynomial is the product of it's factors.

here the roots are x = 4, x = - 5 and x =  7, hence

(x - 4), (x + 5) and (x - 7) are the factors

f(x) = a(x - 4)(x + 5)(x - 7) ← a is a multiplier

let a = 1 and expand the factors

f(x) = (x² + x - 20)(x - 7)

     = x³ + x² - 20x - 7x² - 7x + 140

     = x³ - 6x² - 27x + 140 → A
