Find the product and simplify. 5/16 of 24/15

1/2

Step-by-step explanation:

First, write out the product.  Then, reduce as far as possible:

5       24         5(1)(4)(6)

* =   Here, the 5s cancel, and so we get:

16       15         5(3)(4)(4)

4(6)

3(4)(4)

Here, the 4 in the numerator cancels out one of the 4s in the denominator:

 6

12

and this last result reduces to 1/2.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
