-6+3= -3
3/7+2/7=5/7
The answer is -3 5/7
Please mark as brainliest.
B would be 11 (if thats what youre asking)
Hope this helps!
Answer:
I believe its the second one but i could be wrong
3x+7 = 51-x
4x = 44
x = 11
answer
x = 11
a = 3, b= - 4 and c = - 4
expand the left side using FOIL
(2x + 1)(ax + b) = 2ax² + 2bx + ax + b = 2ax² + x(2b + a) + b
compare the coefficients of expressions on left and right sides.
compare 2ax² + x(2b +a) + b with 6x² - 5x + c
coefficients of x² terms → 2a = 6 ⇒ a = 3
coefficients of x terms → 2b + a = - 5 → 2b + 3 = - 5 → 2b = - 8 ⇒ b = - 4
constant terms c = b = - 4
