Answer:
I think A
Step-by-step explanation:
Answer:
- 3y² - 7y + 6
Step-by-step explanation:
Given
(- 3y + 2)(y + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
- 3y (y + 3) + 2(y + 3) ← distribute both parenthesis
= - 3y² - 9y + 2y + 6 ← collect like terms
= - 3y² - 7y + 6
Answer:
<A = ( 4 * 32 - 13 ) = 115
<C = ( x + 18 ) = 50
Step-by-step explanation:
(4x - 13 ) + 15 + ( x + 18 ) = 180 ( because the total angle of a triangle is 180)
5x + 20 = 180
5x = 160
x = 32
Answer:
It would be C. I and II
Step-by-step explanation:
Answer:
Option C (4096π in²)
Step-by-step explanation:
Area of the circle = 256π in²
We know that 
, where r = radius of the circle
So,
Cancelling π from both the sides,
The radius of the circle = 16 in.
When the radius is multiplied with 4 , new radius = 16×4 = 64 in.
New Area =
