Answer:

41

Step-by-step explanation:

b^2 - 2ac                plug in the values

3^2 -2(4)(-4)             start with the exponent (remember PEMDAS)

9  -2(4)(-4)                start multiplying from left to right

9  -8(-4)                    multiply

9 + 32                       add

41                              that's your answer :)

Pythagorean theorem in 3D
kiruha [24]

Answer:

d = 6.997 or 7

Step-by-step explanation:

Use Pythagorean Theorem to find the diagonal of the end of the prism

2^2 + 3^2 = C^2     Simplify

4 + 9 = C^2             Add

13 = C^2                  Take the square root of both sides

3.6 = C

Now plug this into the Pythagorean Theorem equation for the diagonal of the whole prism.

3.6^2 + 6^2 = d^2     Simplify

12.96 + 36 = d^2       Add

48.96 = d^2               Take the square root of both sides

6.997 = d                   This can be rounded up to 7, if needed

A coat regularly cost $125 is put on sale for $75
Stels [109]
If a coat is regularly $125, and they mark it down to $75, we could figure out how much money was taken off by subtracting $75, from $125

$125 - $75 = $50

So the coats price was cut by $50.

Hope it helps
