Answer:
$9.03
Step-by-step explanation:
Using x for pay rate
63.24=7x Divide both sides by 7
x=9.03
The answer is:
14.875
Hope this helps
The answer is A, 16. Here's some work:
6x + 2 = 98
6x = 96
x = 16
Answer:
Y=21
X=8
Step-by-step explanation:
In the middle there is a right angle
therefore 27 +3y=90
Y will be 21
Then x+27+63+8x+18=180
x=8
Hence 8+27+3(21)+8(8)+18=180
X^4 - 5x^2 - 36 = 0
(x^2 - 9)(x^2 + 4) = 0 - factor the left side
(x + 3)(x - 3)(x^2 + 4) = 0 - factor (x^2 - 9 as difference of squares)
x + 3 = 0 x - 3 = 0 x^2 + 4 = 0 Set each factor to 0 if any 0 the left side 0
x = -3 x = 3 x^2 = -4
x = 2i or -2i
The roots are 3, -3, 2i, -2i (Don't know if you need the imaginary roots but I gave you them anyway)
