Answer:

roots:   -2   and 5

Step-by-step explanation:

What are the roots of y = x2 – 3x - 10?

we see...

factor  -10 ....    using the X-method.

-10 =  2 * -5

where  2 + -5 = -3

so

y = (x +2)(x - 5)

roots are  -2 and 5

Answer:

440 square inches.

Explanation:

We can consider the boxes as one single shape.

So it's base area is 12×10=120 and the area of the side faces is 20×12=240 and 20×10=200.

Now, there are 2 of each, so let's add up everything and multiply by 2.

(120+240+200)×3=560 square inches.

But we have to take off the base, so:

560-120=440 square inches

Answer:

<COB = 50°

Step-by-step explanation:

We can say that m<AOC + m<COD + m<DOB = 180° because the three mentioned angles form a straight line. We can substitute to get:

3x + 94 + x + 18 + 2x - 4 = 180

Then, we can combine like terms:

6x + 108 = 180

6x = 72

x = 12

We can see that m<COB is the sum of m<COD and m<DOB. We can wrote an equation to model the situation:

m<COB = m<COD + m<DOB

m<COB = x + 18 + 2x - 4

m<COB = 3x + 14

We have the value of x, so we can substitute that in:

<COB = 3(12) + 14

<COB = 36 + 14

<COB = 50°
