Answer:
18.84 square inches
Step-by-step explanation:
Distance across = diameter. The area formula for circles is A= πr. r in here means radius which is 6 inches (half of diameter). π is generally 3.14 or 22/7 depending on the question. multiply the value of π and 6, then you get the answer.
Answer:
D. 30 sq in.
Step-by-step explanation:
10+9+6+5=30 sq in.
The pic is blurry, but looks like 18x²-21x-15
(3x-5)(6x+3) is the factored form.
3 and 6 are the factors of 18
-5, 3 or -3, 5 are the factors of -15
I line them up like this
3 -5
6 3
then I multiple them diagonally: 3*3=9, -5*6=-30, the sum of 9 and -30 is exactly -21, the coefficient for x. (If the sum doesn't make -21, I'd switch -5 and 3, or change to -3 and 5 to try again.)
so the factored form is (3x-5)(6x+3)
Divide both sides by f then cancel out
Answer:
Quadrant II - +
Step-by-step explanation:
3,-4 translated 5 up is 3,1 then 4 units left is -1,1
