Answer:

(x - 1) (3 x - 8)

Step-by-step explanation:

Factor the following:

3 x^2 - 11 x + 8

Factor the quadratic 3 x^2 - 11 x + 8. The coefficient of x^2 is 3 and the constant term is 8. The product of 3 and 8 is 24. The factors of 24 which sum to -11 are -3 and -8. So 3 x^2 - 11 x + 8 = 3 x^2 - 8 x - 3 x + 8 = 3 x (x - 1) - 8 (x - 1):

3 x (x - 1) - 8 (x - 1)

Factor x - 1 from 3 x (x - 1) - 8 (x - 1):

Answer: (x - 1) (3 x - 8)

Find the missing side length, m.
algol [13]

Answer:

m=6

Step-by-step explanation:

The Two triangles are Similar, so using the property of the similar triangles.

                   \frac{m}{15} =\frac{4}{10}

On cross multiplication of the fraction:

                10*m=4*15

                10*m=60\\\\

Dividing by '10' both the sides:

                \frac{10m}{10}=\frac{60}{10}

                 m=6

So, the side(m) of the small triangle is '6'

If sin p =3/5 and p is an acute angle, what is the value of tan p?
Leya [2.2K]

Answer:

sin x + cos x = 5/13 + 12/13

Step-by-step explanation:

Given that tan x = 5/12, what is the value of sin x + cos x?

draw a triangle with opposite leg=3 and hypotenuse=5

tan p = opposite/adjacent = 3/4

similarly, in a 5-12-13 right triangle

sin x + cos x = 5/13 + 12/13

A gym teacher has 250 to spend on volleyball, she buys for volleyball nets that cost $28 volleyballs are $7 each.how many volley
MaRussiya [10]

The gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyballs cost $7 each. How many volley balls can she buy

Answer:

she can buy maximum of 19 balls.

Step-by-step explanation:

Let the number of volleyballs  be x

we know that

\text{(The cost of each volleyball net} \times \text{number of volleyball net)}+\text{(the cost of each volleyball} \times \text{number of volleyballs)}\leq \ 250

so substituting the values,

28(4) + 7x \leq 250

112 + 7x \leq 250

7x \leq 250 - 112

7x \leq 138

x \leq \frac{138}{7}

x \leq 19.7
