If the area of the rectangle is given by the polynomial 2x^2-7x-15, what is the dimension of the reactangle in terms of x?​

Answers

Answer 1

Answer:

x - 5 and 2x + 3

Step-by-step explanation:

GivenArea of rectangle = 2x^2 - 7x - 15To findDimensions of rectangleSolution

Since the area is the product of the sides, let's try to factorize the given:

2x^2 - 7x - 15= 2x^2 - 10x + 3x - 15 =2x(x - 5) + 3(x - 5) =(x - 5)(2x + 3)

So the dimensions are:

x - 5 and 2x + 3

Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result, he has decided to use FedEx to deliver many of his gifts this year. FedEx charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones's was $28.85, how much did their gifts weigh?

Answers

Answer:

31 pounds

Step-by-step explanation:

From the information given, you can write the following formula to calculate the total cost of sending gifts:

Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds

Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:

28.85=2.50+0.85x

28.85-2.50=0.85x

26.35=0.85x

x=26.35/0.85

x=31

According to this, the answer is that the gifts weighed 31 pounds.

Use the literal equation m=5/4n-7 to find m when n =40

Help plz

Answers

Answer: 5/153

Step-by-step explanation:

Well, you'd just have to plug in 40 for n.

5/(40*4 - 7) = m

5/(160-7) = m

5/153 = m

An equation is formed of two equal expressions. As per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of m from the given equation can be found by substituting the value of n as 7 in the given equation as shown below.

m = (5/4)n - 7

Substitute the value of n as 40,

m = (5/4)40 - 7

m = (5/1)10 - 7

m = 50 - 7

m = 42

Hence, as per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.
