Hi,
Answer: (x+5)^2
<u>My work:</u> For this problem can be easily achieved by factoring your terms. To do this you figure out what can go into 10x and 25 which is 5. From the there you take x^2 and 10x and see what can take out which would be x. Your answer would be (x + 5)^2 or (x +5) (x + 5). This can be done in 2 easy steps!
<u><em>Numerical work:</em></u>
1.x^2 10x +25
Before this step figure out what goes into you equation.
2. (X + 5)^2 or (X+5) (X + 5)
The slope is -3/2 and the y-intercept is -3. If you need me to explain I can do that :) hope this helps
Answer:
A=80 pounds, B=63 pounds
Step-by-step explanation:
Cost of type A=$4.35 per pound
Cost of type B=$5.80 per pound
Cost of A+ B=$713.40
A+B=143 pounds
A=143-B
QaPa+QbPb=713.40
A*4.35 + B*5.80=713.40
4.35A+5.80B=713.40
Substitute A=143-B
4.35(143-B) + 5.80B=713.40
622.05 - 4.35B + 5.80B=713.40
1.45B=713.40-622.05
1.45B=91.35
B=91.35/1.45
=63
B=63
Recall,
A+B=143
A+63=143
A=143-63
=80
A=80 pounds, B=63 pounds
