Answer: His mom's age is 48

Step-by-step explanation: If his age is 1/4 his mother, then if we know his age, we do the opposite. Multiply his age by 4, we get 48.

Find the measure of angle A. This is for my math class, and I’ve been stuck on this for a while. Please help!
Kruka [31]

Answer:

20°

Step-by-step explanation:

The sum of angles in a ∆ = 180°

Therefore, (17x - 1) + (3x - 4) + 25 = 180

Use this expression to find the value of x, then find the measure of angle A.

17x - 1 + 3x - 4 + 25 = 180

17x + 3x - 1 - 4 + 25 = 180

20x + 20 = 180

Subtract 20 from both sides

20x + 20 - 20 = 180 - 20

20x = 160

Divide both sides by 20

\frac{20x} = \frac{160}{20}

x = 8

Find measure of angle A.

Angle A is given as 3x - 4

Plug in the value of x and solve

A = 3(8) - 4 = 24 - 4 = 20

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24
ludmilkaskok [199]

For this case we have the following polynomial:

60x ^ 2 + 48x + 24

What we must do for this case is to factor the polynomial, so that we have:

1) The number of bottles

2) the weight of each bottle.

We have then:

12 (5x ^ 2 + 4x + 2)

Answer:

A factorization that could represent the number of water bottles and weight of each water bottle is:

12 (5x ^ 2 + 4x + 2)
