Slope= y^2-y^1
————
x^2-x^1
slope= 12-0
——-
6+2
slope= 12

8
slope= 3/2
perpendicular slope is the opposite reciprocal
perpendicular slope= -2/3
In step 1, the commutative property of addition is used since x + 5 is just equal to 5 + x
In step 2, the associative property of addition is used since x is grouped to the last term.
In step 3, the distributive property of multiplication is used since 3 is multiplied to the terms inside the parenthesis.
In step 4, multiplication is done.
Answer:
422.4cm²
Step-by-step explanation:
area of circle is pi x 12² which is 144 pi
144pi subtract 30 is 422.4
Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
