Answer:
it’s a multi step equation
Step-by-step explanation:
solve like a multi step
32=w+y, w=32-y...
11.95w+11.5y=373.4, using w from above gives us:
11.95(32-y)+11.5y=373.4
382.4-11.95y+11.5y=373.4
-.45y=-9
y=20
So 20 yellow and (32-20) 12 white shirts were sold.
You can either use the Pythagorean theorem right away (a = -3, b = 27, c = 1200) or Try factoring the polynomial to find the zeros.
I would factor and start by dividing everything by -3.
<span>-3x^4 + 27x^2 + 1200 = 0
-3(x^4 - 9x^2 - 400) = 0
If you divide by -3 on both sides you see that the -3 is now gone. 0/-3 = 0
x^4 - 9x^2 - 400 = 0
factor further or use Pythagorean theorem.
(x² - 25)(x² + 16) = 0
Solve for the x-values by setting each one equal to zero.
x² - 25 = 0
x² = 25
x is +5 or -5
x² + 16 = 0
x² = -16
x = √(-16)
Two non-real solutions
x is +4i or -4i

Answer:
256 π cu in
Step-by-step explanation:
We have a regular sphere with a radius of 8 inches.
The surface area of such sphere is given by the formula:
A = 4 * π * r²
So, in our case, we have:
A = 4 * π * 8² = 4 * 64 * π = 256 π cubic inches.
We'll stop the calculation there since it was looking for an answer expressed with π.
I hope that helps you.
I think 100 is the answer I’m not sure
