Answer:

-24a² - 42a - 28

Simplified form =  12a² + 21a + 14

Step-by-step explanation:

-4(7 + 3a) - 6a(4a - 5) (distribute -4)

-28 - 12a -6a(4a - 5) (distribute -6a)

-28 - 12a -24a² - 30a (collect like terms)

-24a² - 42a - 28

We can simplify

-24a² - 42a - 28 (divide -2)

12a² + 21a + 14

Hope this helps ya! Keep smiling!

Find the length of GF
Cerrena [4.2K]
By the Pythagorean Theorem:

The square of the hypotenuse (longest side) of a right triangle is equal to the sum of the side lengths squared, or mathematically:

h^2=x^2+y^2, where x and y are the side lengths and h is the length of the hypotenuse, in this case:

9.4^2=6.8^2+GF^2

GF^2=9.4^2-6.8^2

GF^2=42.12

GF=√42.12 units

GF≈6.49 units (to nearest hundredth of a unit)
