The length of consecutive sides of a rectangle are represented by 2x+1 and 3x+2.Express the area of the rectangle in terms of x

Answers

Hello AnneBunny!

The area of a rectangle is the base multiplied by its height.

The answer is  6x^2+7x+2

Thus, (2x+1)(3x+2) is equal to 6x^2+7x+2

Cheers!

How many quarts is 2.5 gallons

Answers

2.5 gallons 
how many quarts?

1 gallon = 4 quarts

Make proportions:
(1)/(4) = (2.5)/(q)
2.5 × 4 = 1q
10 quarts = q

2.5 gallons = 10 quarts
The answer would be: 10 quarts

Choose the equation that represents a line that passes through points (−6, 4) and (2, 0). x + 2y = 2 2x − y = −16 x + 2y = −8 2x + y = 4

Answers

Answer:

x + 2y = 2

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

================================================

We have the points (-6, 4) and (2, 0).

Substitute:

m=(0-4)/(2-(-6))=(-4)/(8)=-(1)/(2)

Put the value of the slope and coordinates of the point (2, 0) to the equation of a line:

0=-(1)/(2)(2)+b

0=-1+b          add 1 to both sides

1=b\to b=1

The equation of a line in the slope-intercept form:

y=-(1)/(2)x+1

Convert to the standard form Ax+By=C

y=-(1)/(2)x+1           multiply both sides by 2

2y=-x+2             add x to both sides

x+2y=2

Answer:

Option 1.

Step-by-step explanation:

It is given that the line passes through the points (-6,4) and (2,0).

If a line passes through two points, then the equation of line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

Using the above formula the equation of line is

y-(4)=(0-4)/(2-(-6))(x-(-6))

y-4=(-4)/(8)(x+6)

y-4=(-1)/(2)(x+6)

Muliply both sides by 2.

2y-8=-x-6

x+2y=-6+8

x+2y=2

Therefore, the correct option is 1.

True or false:x/3 is equivalent to 1/3x.explain your reasoning.

Answers

Yes, both the expressions are equivalent.

What is an expression?

An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation. This maths operation can be addition, subtraction, multiplication, or division.

Given that, x/3 is equivalent to 1/3x, yes or not?

So, we can write x/3 as

1/3×x

= x/3

Since, either you multiply by 1/3 or divide by 3 both are same thing,

1/3×x = x/3 = 0.333x

for example; 4÷2 = 2 or 4×1/2 = 2, in both case the answer is same, that means the expression given are also equal.

Hence, we can conclude both the expressions are equivalent.
