Answer:
<h2>8x - 1</h2>
Step-by-step explanation:
Four x: 4x
Two x: 2x
Two times two x: 2(2x) = 4x
Four x plus two times two x minus one: 4x + 2(2x) - 1 = 4x + 4x - 1
<em>Combine like terms:</em> = (4x + 4x) - 1 = 8x - 1
Let's check your answer. To do this, you would simply plug your answer into the equation and see if it works.
5(y - 3) - 2 (3 - 2y) = 6
5(3 - 3) - 2(3 - 2 × 3) = 6
The equation works!
Y = 3
Great work!
The volume of a pyramid is one-third of the product of its altitude and area of the base.
Area of the base = (8 in)² = 64 in²
Altitude:
The altitude is the length of the right triangle formed from the base and the slant height as the hypotenuse.
(5 in)² = h² + (4 in)²
h = 3 in
Volume:
V = Ah/3
V = (64 in²)(9 in) / 3 = 192 in³
The volume of the solid right pyramid is equal to <em>192 in³</em>.
