Answer:
$148.65
Step-by-step explanation:
8.875% = 14.4777875,
so the sales tax is $14.48.
$163.13 - $14.48 = 148.6522125,
so the total before sales tax is $148.65.
2(x - 3) + 21 = -3
2x - 6 + 21 = -3
2x + 15 = -3
2x = -18
x = -9
x needs to be -9 to make the equation true.

Answer:
Solution given:
Since it is a form of (a+b)²
we have
(a+b)²=a²+2ab+b²
here
a=x
b=b/2a
now
substituting value
x²+2*x*b/2a+(b/2a)²
|x-3|+5
With absolute value you're going to always use these | |
If you wish to go to right you will subtract x, if you wish to go to the left you will add to x.
And the +5 will do as it says and go up 5 or -5 go down by 5.
area=3136sq.cm
height=perpendicular=64 cm
base=?
area=1/2*base*height
3136=1/2*base*64
therefore,, base=98
