Answer:
999
Step-by-step explanation:
x - 13 = 1012
x= 999
A^2+b^2=C^2
13^2+b^2=21^2
169+b^2=441 collect the like terms
b^2=441-169
b^2=272 get the square root of b and 272
b=16.492422
b=16.5 choice B
Answer:
9 & 6
Step-by-step explanation:
First, check if, by adding them (sum), they equal 15:
9 + 6 = 15
Next, check the greater number, by multiplying it by 2:
9 x 2 = 18
Check the lesser number, by multiplying it by 3:
6 x 3 = 18
Note that they both have 18 as an answer.
9 & 6 are your answers.

Answer:
Below.
Step-by-step explanation:
7cm
(r) = 3.5cm
l = 5.5cm
Arc length = (Ѳ/360)2∏r
5.5 = (Ѳ/360)2*3.14*3.5
5.5 = (Ѳ/360)21.98
Divide 21.98.
5.5/21.98 = Ѳ/360
Ѳ/360 = 0.25
x 360.
Ѳ = 90
Arc angle is 90 degrees.
-8 + 5 = -3
I attached a photo of a number line I drew. If you move up 5 spaces from -8, then you’ll be at -3.
