Expand and simplify these 6 questions
first one: 2(1x + 3) - 5
second one: 3(1x + 7) + 3x
third one: 4(1x + 2) + 8
fourth one: 4(1x + 1) - 6
fifth one: 2(3x + 2) - 5x
sixth one: 5(1x - 4) + 10

Answers

Answer 1
First one: divide multiply 2(1x) which would equal 2x then do 2*3 then u would subtract 5 which should get you to the simplified form 2x+1

Second one: do 3(1x) which would equal 3x then do 7*3 which would equal 21 than do plus 3x which should get you to the simplified form of 6x+21

Third one: Do 4(1x) which equals 4x than do 4*2 which equals 8 than plus eight which should get you to the simplest form of 4x+16

Fourth one: do 4(1x) which would equal 4x then do 4*1 which equals 4 than subtract 6 which should get you to the simplest form of 4x-2

Fifth one: do 2(3x) which equals 6x then do 2*2 which equals 4 than subtract 5x which should get you to the simplest form of x+4

Sixth one: do 5(1x) which equals 5x than do 5*-4 which equals -20 than add 10 which gets you to the simplest form of 5x-10

In the diagram, line GH is perpendicular to line IJ. What is the measure of angle 1?


A. 37°
B. 53°
C. 63°
D. 74°

Answers

Answer: B

Explanation: 37+53= 90 and it being perpendicular creates a right angle of 90 degrees
Answer is 53 because these are supplementary angles and they adapt to 180 degrees. You add 37 and 90= 127, and then you subtract 127 from 180.

In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 16, 18, 18, 24, 25, 27, 28, 31, 31, and 32. Jean made the qualitative statement, "The average weight of the raccoon population is 26 pounds." Is her statement reasonable? Complete the explanation.

Jean's statement (select) reasonable because the median value of the data is pounds.

Answers

Answer:

The average is 24 so her answer is reasonable cause it is not too far off.

Step-by-step explanation:

Average = sum/count

(16 + 18 + 18 + 24 + 25 + 27 + 28 + 31 + 31 + 32)/10

240/10

24

24 is close to 26

(2m-7)(2m-7)
4m^2 - 14m - 14m + 49
4m^2 - 28m + 49

Answer: 4m²-28m+49

Step-by-step explanation:

(2m-7)² can be written as (2m-7)(2m-7).

You would have to multiply it out like this:

2m times 2m=4m² (2x2=4 and mxm=m²)

2m times -7=-14m (2x-7=-14 then put a m on it)

-7 times 2m=-14m

-7 times -7=49

The equation would then look like this:

4m²-14m-14m+49

Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:

4m²-28m+49

Hope this helps :)

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The marked angle in 2 different ways will be given as,

The first way will be

∠HLK or ∠KHL

The second way will be

∠KHL = ∠HLJ - ∠KLJ

736 square feet

We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.

The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96


Add them all up: 400 + 240 + 96 = 736 square feet

Write an equation that you can use to solve for x.

Enter your answer in the box.

Answers

Answer:

27 Degrees

Step-by-step explanation:

Since 63 and x make 90 degrees, 90-63 is 27 which gives you the answer. The equation is X=90-63.

Answer:

63 + x = 90

Step-by-step explanation:

The desired equation is 63 + x = 90, because the angles 63 and x are complementary (they add up to 90 degrees).

Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why?

Answers

Answer:

The answer is "C"

Step-by-step explanation:

Answer:

Answer C.  This point lies between the two axes and its coordinates satisfy both equations

Step-by-step explanation:

Line A: y = x − 4

Line B: y = 3x + 4

Let's actually solve this system, using substitution:  Equate

Line A: y = x − 4   to   Line B: y = 3x + 4, obtaining:

                  x − 4  =     3x + 4

Subtract (x - 4) from both sides.  Doing so yields

                         0 = 2x + 8, and so x = -4.

From Line A let's find y:   Letting x = -4, we get:  y = -4 - 4 = -8

and so the solution is (-4, -8).  This matches Answer C.  This point lies between the two axes and its coordinates satisfy both equations.
