Answer:
74-27q
Step-by-step explanation:
8(10 - 6q) + 3(7q - 2)
use the distributive property to get rid of the parenthesis
(8*10) - (8*6q) + (3*7q) - (3*2)
80 - 48q + 21q - 6
combine like terms
(80 - 6) - 48q + 21q
74 - 27q :)
Answer:
A.
Step-by-step explanation:
Answer: 24cm
Step-by-step explanation:
Inradius = r
c = the hypothenuse
a & b = the other 2 sides of the triangle
Inradius formula: r = 1/2 * (a+b-c)
Plug in what we know.
2 = 1/2 * (a+b-10)
Multiply both sides by 2.
2*2 = 1/2 * (a+b-10) * 2
4 = a+b-10
Add 10 to both sides.
4+10 = a+b-10+10
14 = a+b
Perimeter formula: P=a+b+c
Plug in what we know
(remember a+b=14).
P=14 + 10
P = 24
Answer:
Step-by-step explanation:
Substitute m=(2x+1) and n=(6) in m+n=(9).
We are finding the value of the x variable.
Add the numbers on the left side of the equation.
Subtract 7 from both sides.
Divide both sides by 2.
The value of the x variable is 1.
