Answer:
Step-by-step explanation:
R means Rosa
given:
R+b+c=36
R R c-2=b, (R+2)+2=c
b-2=R, R+2=b
.
R+b+c=36 substitute for b and c
R+(R+2)+((R+2)+2)=36 add like terms
3R+6=36 subtract 6
3R=30 divide by 3
R=10
.
check
R=10
b=12
c=14
10+12+14=36
36=36
1. Given
2. Combine like terms
3. Subtraction POE (Property of Equality)
Answer:
7; not a factor
Step-by-step explanation:
2x³ - x² - 4x² + 2x + 6x - 3 + 7
x²(2x-1) - 2x(2x-1) + 3(2x-1) + 7
7 is the remainder.
Hence, not a factor
B. 5, 9
x = 5
y = 9
y - x = 4
(9) - (5) = 4
True
hope this helps
