Factor each expression 4x+ 16 and -6y + 18

Answers

When we factor, we bring the term into its simplest form.

4x + 16 = 4(x + 4)
To check:
4x + 4*4 = 4x + 16

-6y + 18 = -6(y - 3)
To check:
-6y + (-6)(-3) = -6y + 18

$4x+ 16 \n \n GCF = 4 \n \n 4( (4x)/(4) + (16)/(4) ) \n \n 4(x + 4) \n \n$

The final result is: 4(x + 4).

--------

$-6y + 18 \n \n GCF = 6 \n \n 6( (6y)/(6) - (18)/(6) ) \n \n -6(y - 3) \n \n$

The final result is: -6(y - 3).

Volume of this prism

Answers

The volume is (area of cross-section) x (length) .

-- The cross-section is a triangle. The area of a triangle is

Area = (1/2) (base) (height) .

In this one, the base is 9/4 m and the height is 3-1/3 m .

Area = (1/2) (9/4 m) (3-1/3 m)

Area = (1/2) (9/4) (10/3)

Area = 90/24 m² .

-- Volume = (area of cross-section) x (length)

Volume = (90/24 m²) x (7-1/3 m)

Volume = (90/24) x (22/3) m³

Volume = (1,980 / 72) m³

Volume = 27.5 m³
