Answer:x= 5/2 x= -1/2
Step-by-step explanation:
4(x-1)2-9
4(x2-2x+1) - 9
4x2 - 8x + 4 - 9
4x2 - 8x - 5
4x2 +2x - 10x - 5
2x(2x+1) - 5(2x+1)
(2x-5)(2x+1)
therefore, x= 5/2 x= -1/2

Answer:
1.15p + 285 = 5.84
Step-by-step explanation:
This problem has two equations. Total cost and Total pounds. The cost and the pounds
p = apple pounds
b = banana pounds
<u>Cost</u>
1.90p + .75b = 5.84
<u>Pounds</u>
p + b = 3.8
<u>Now we use the substitute method for system of equations to solve</u>
p + b = 3.8
b = -p + 3.8
<u>Now that we know what b equals, substitute is for b in the cost equation.</u>
1.90p + .75b = 5.84
1.90p + .75(-p+3.8) = 5.84
<u>distribute / multiply .75 by (-p+3.8)</u>
1.90p + -.75p + 2.85 = 5.84
<u>Combine the p values</u>
1.15p + 285 = 5.84
