Answer:
Find the area of the semi circle with Diameter of 4
2π
6.3
Step-by-step explanation:
The area formula for semicircle is (πr^2)/2.
r=2 because radius is half of diameter.
(π(2)^2)/2, 2 squared= 4 and half of it is 2. = 2π
2π would round to the nearest tenths is 6.3.
Answer: 28 and 18
Step-by-step explanation:
I used the guess and test strategy to find that:
28 - 10 = 18
28 + 18 = 46
<span>7x - 5 = 2
add 5 to both sides
</span><span>7x - 5+5 = 2+5
7x=7
Divide both sides by 7 to get x by itself
x=1 </span>
<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
