Square root 270 a^2 b^2
3sq root 30 a^2b^
The answer is C.
x^2 + z = 103x^2 + 22 = 103*Subtract both sides by 22*x^2 + 22 - 22 = 103 - 22x^2 = 81*square root both sides to find x*√x^2 = <span>√81</span>
<span>x = +- 9</span>
Answer:
2,750+170d
Step-by-step explanation:
Calculation to Enter and simplify an expression for the amount in dollars that the company is paid
First step
Let d represent numbers of day
15(100+3d)
Second step is the Expression for the food booths
25(50+5d)
Third step is Expression for the game booths
15(100+3d)+25(50+5d)
Fourth step is the Expression for both game and food booths
15*100+15*3d+25*50+25*5d
=1,500+45d+1,250+125d
Fifth step is to make use of distributive Property
1,500+1,250+45d+125d
Last step is to make use of cumulative property
(1,500+1,250)+(45d+125d)
=2,750+170d (combine like terms)
Therefore expression for the amount in dollars that the company is paid is 2,750+170d
