Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{10 {x}^{2} + 26x + 12}}}}}$

Step-by-step explanation:

$\sf{(5x + 3)(2x + 4)}$

Use distribute property to multiply each term of the first binomial by each term of the second binomial.

$\dashrightarrow{ \sf{5x(2x + 4) + 3(2x + 4)}}$

$\dashrightarrow{ \sf{10 {x}^{2} + 20x + 6x + 12}}$

Collect like terms

$\dashrightarrow{ \sf{10 {x}^{2} + 26x + 12}}$

Hope I helped !

Best regards! :D

3.25-2.5-------> 0.75 liters--------> 750 mi
the statement is false

4b. Fred brought 1.75 liters more laundry detergent than bleach
4-2.5---------> 1.5 liters
the statement is false

FIRST ANSWER GETS BRANLIEST

There are two steps to this problem. The first step is to make an equation for the cost of each company. The cost of each one involves 2 variables. However, we can ignore the number of days since the question asks for per day.

CostA = 90 + .40(miles)

CostB = 30 + .70(miles)

We want to know when A is a better deal or when A costs less. That is when CostA < CostB. We can then substitute the right sides of our equations into the inequality. This will give:

90 + .40(miles) < 30 + .70(miles) This is where we will now begin to solve for the number of miles.

-30 -30 Subtract 30 from both sides.

60 + .4(miles) < .7(miles) Simplify

-.4(miles) -.4(miles) Subtract .4(miles) from both sides

60 < .3(miles) Simplify

/.3 /.3 Divide both sides by .3

200 < miles Simplify

So for A to cost less the number of miles must be greater than 200.

1/4 # hamburger = 16 oz to a pound so 1/4 is 4 oz.

1 doz baseballs (12), 5 oz each

Box = 9 oz.

Total weight = 12x5 = 60 oz. + 9 oz. = 69 oz.

69/16 = 4 lb. 5 oz.

By definition we have that the average rate of change of the function is:

$AVR = \frac{f(x2) - f(x1)}{x2 - x1}$
