Answer:
-2
Step-by-step explanation:
9 & -5
If you graph the equation and look at where the x intercepts are that will give you the answer
from the equation<span> x^2 - 6x + 7 = 0 </span>, b is equal to -6. The form should become y = (x-(b/2)^2) + c. (<span>b/2)^2 is equal to 9. Hence,
</span>
0 = (x - 3)^2 -9 + 7
<span>0 = (x - 3)^2 -2
</span>2 = <span>(x - 3)^2
x should be equal to -1.5858 and -4.4142</span>
Answer:
Each pipe is 24m
Step-by-step explanation:
<u>Given:</u>
- three pipes
- combined equal 72m
- let the variable x represent the length of 1 pipe
<u>Algebraic Expression</u>:
3 pipes times length equals 72m (the total length)
3x = 72, we want x to be alone so divided both sides by 3
3x / 3 = 72 / 3
x = 24
