A. 2 parts is 7, so 7/2 is 3.5 = 1 part, then multiply by 3 to make the corresponding side which is 10.5 or 10 1/2
Answer:
11(9 - 2) - 3
Step-by-step explanation:
This is how you write the expression.
Three less means we have a -3.
11 times the sum of 9 - 2 means we have 11(9 - 2)
We put these together to get:
-3 + 11(9 - 2)
Or we can simplify it to:
11(9 - 2) - 3
This is just simple Pythagorean’s theorem. a^2 + b^2 = c^2
Number 2:
5^2 + x^2 = 10^2
25 + x^2 = 100
x^2 = 75
x = sqrt 75 = 5*sqrt(3)
Number 3:
4^2 + x^2 = 7^2
16 + x^2 = 49
x^2 = 33
x = sqrt 33
Answer:
Step-by-step explanation:
(x,y)→(x+5,y)
(-4,-1)→(-4+5,-1)=(1,-1)
reflection about x-axis
(x,y)→(x,-y)
(1,-1)→(1,1)
