Answer:
75 and 552 =627
Step-by-step explanation:
First=x
Second 7x+27
x+ 7x+27= 627
8x+27=627
8x=600
x=75
75*7+27 =525
525+27 = 552
Answer:
-2 I think
Step-by-step explanation:
7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
