Hello there ^ _ ^
121x² + 64 = 0
121x² = 0 - 64
121x² = -64
x² = 64/121
Now take square root
x = +/-√-64/121
I hope this help!
Answer: the employee must make sales of $32000
Step-by-step explanation:
Let x represent the total sales that the employee makes in a month.
One employee of a computer store is paid a base salary of $2,000 a month plus an 8% commission on all sales over $7,000 during the month. This means that if the employee makes sales of $x in a month, his total earnings for that month would be
2000 + 8/100(x - 7000)
= 2000 + 0.08(x - 7000)
= 2000 + 0.08x - 560
= 0.08x + 1440
Therefore, for the employee to earn
a total of $4,000 for the month, the amount of sales would be
0.08x + 1440 = 4000
0.08x = 4000 - 1440
0.08x = 2560
x = 2560/0.08
x = $32000

Step-by-step explanation:
The number of tubes can be found from an inequality that relates the number of square inches that can be painted to the number of square inches that must be painted.
Let t represent the number of tubes.
1400t ≥ 3672 . . . . . the number of tubes that will paint at least 3672 in²
t > 2.623 . . . . . divide by 1400
If only whole numbers of tubes are available, then ...
3 tubes are needed to paint the ramp.
A=lw and A=bh are the same equation in terms of a square you just need to simply think of the swuare as standing up with bh and lw as laying down
they both work
