Answer:
B. x^2 + 1
Step-by-step explanation:
Because squaring the value of 1 does not change its value, the equation would function the same way the original equation if x was the only value squared.
Your two equations would be:
150 = x + y
2560 = 20x + 12y
after solving,
95 for $20
55 for $12
X/6+3=-18
multiply both sides by six
x+18=108
move constant to the right
x=-108-18
calculate
solution: x=-126
The easiest way to find the expansion of the expression given would e to distribute. To distribute, you have to multiply each of the terms in the parentheses by 9. The expansion of the expression would be 9x + 18.
9 (x + 2)
9 · x = 9x
9 · 2 = 18
9x + 18
Hope this helps. Good luck! :)
150 is the amount of interest earned for one year because the formula of PRT is, in this case 5000 times 0.03 times one which gets you the answer of 150.
