Answer: Triangle 3 is not a right triangle
Step-by-step explanation:
The sides should be able to put into the Pythagorean Theorem if it is a right triangle
Triangle 1: 6, 8, 10... 36+64=100-- true statement
Triangle 2: 6, 10, 12 ... 36+100 - 144-- incorrect statement
Triangle 3: 9, 12, 15... 81+144= 225-- true Statement
Triangle 4: 12, 16, 20... 144+256=400-- true statement
C = 5/9(F - 32)....multiply both sides by 9/5
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F
Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
The sum could be greater than 1 but not equal to 1.
Answer:
A
Step-by-step explanation:
first lets find the area of the square
A=l*w
12*12=144 m^2
then lets find the are of the circle
A=pi*r^2
A=3.14*(d/2)^2
the diameter of the circle is 12m
A=3.14*(12/2)^2
A=3.14*(6)^2
A=3.14*36
A=113.04 m^2
Now, lets subtract the area of the circle form the area of the square
144-113.04= 30.96 m^2
So, the answer is A
