Answer:
14x + 4
Step-by-step explanation:
3(4x+2) + 2(x-1)
Distribute by multiplying into the bracket
=12x + 6 + 2x - 2
Group like terms by adding and subtracting
= 14x + 4
Answer:
1) Multiply and expand the brackets:
12x + 6 + 2x - 2
2) Combine like terms (combine terms that have an x together, and those that don't together.)
14x + 4
If the question wanted you to simplify the expression, then 14x + 4 is your answer. However, to solve for x, you could equate the expression to 0, but I'm not too sure of this part.
14x + 4 = 0
14x = - 4
x = - 4/14
x = - 2/7

Answer:
x=12
Step-by-step explanation:
Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.
Now looking at the question, we know one side is 90 degree since it is a right triangle.
180-90=90
This let us know that the remaining two angles will have to add up to equal to 90 degrees.
2x+1+5x+5=90
First, combine like terms.
7x+6=90
Now we have to get x by itself, subtract 6 on both sides then divide by 7.
7x=84
x=12
On Saturday, Lucas drove 4x – 5 miles. On Sunday, he drove 3x – 10 miles. What is the difference in miles driven? write an expression and simplify it.
________________________________
Here, Distance covered by Lucas on Saturday
= 4x – 5 miles
Now, Distance covered by Lucas on Sunday
= 3x – 10 miles
________________________________
Hence, Difference between the distances
would be / –
Distance covered on Saturday – Distance covered on Sunday
= (4x – 5) – (3x – 10)
= 4x – 5 – 3x + 10
[ Because (– * + = – ) And ( – * – = +) ]
= 4x – 3x + 10 – 5
= 1x – 5
= x – 5 ( – Ans )
Hence, The difference between Distance covered ( In miles ) is ( x – 5 ) .

The length of the diagonal is
√
12500
, which is 111.80 yards.
The possible dimensions of the sports field are width 70 yards, length 7-3x yards.
What are dimensions?Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.
Given that, the width is at least 50 yards and area is (490-210x)
We can conclude the shape of the sports field is rectangular.
We need to find the Greatest Common factor between 490 and 210, this way:
490 = 2 × 5 × 7 × 7
210 = 2 × 5 × 3 × 7
Then the greatest common factor is 2 × 5 × 7 = 70
This GCF is also equal to 70 yards (given in option), therefore it's one of the dimensions of the sports field.
Now, we calculate the other side of the sports, this way:
Second dimension of the sports field = (490-210x)/70
= 7-3x
Hence, The possible dimensions of the sports field are width 70 yards, length 7-3x yards.

Suppose the two line segments in a coordinate plane one with a length of 120 units and other with a length of 240 units were both rotated 90 degrees about the origin and then translated 50 units up one of the resulting segments could have a length of...Units.
Answer:
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]
Step-by-step explanation:
Given
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]
Transformation
Rotation: 90 degrees
Translation: 50 units up
Required
The new length of one of the lines
Since no options were given, I will solve for the lengths of the two lines
From the question, the transformations are rotation and translation. These two types of translation do not alter the length or angle of a shape.
This implies that both lines will still retain their original lengths.
So. we can conclude that, after the transformation
[tex]Line\ 1 = 120\ units[/tex]
[tex]Line\ 2 = 240\ units[/tex]

Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
Answer:
a) 34.64 inches
b) The TV will not fit inside the TV cabinet
Step-by-step explanation:
Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
We solve using the formula:
Diagonal ² = Width² + Height²
Diagonal = 40 inches
Height = 20 inches
40² = Width² + 20²
Width² = 40² - 20²
Width = √40² - 20²
Width = √(1200)
Width = 34.641016151 inches
Approximately = 34.64 inches
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
From the above calculation, the width of the TV = 34.64 inches
Hence the width of the cabinet has to be equal to or more than 34.64 inches
Hence, The TV will not fit inside the TV cabinet

Step-by-step explanation:
We can only find the range of the values of x by using triangle inequality,

Multiply through both sides by -1, we get,

This means x = -10, -11, ... (which is not realistic because a side of a triangle cannot be a negative number)

A 10-foot ladder touches the side of a building at a point 8 feet above the ground. At what height would a 22-foot ladder touch the building if it makes the same angle with the ground as the shorter ladder? Round to the nearest tenth if necessary.
8.75 feet
Step by step:Given that a 12 foot ladder leans against a building seven feet above the ground.
By using trigonometry ratio, the angle between the ladder and the ground will be
SinØ = opposite/ hypothenus
SinØ = 7 / 12
SinØ = 0.58333
Ø = Sin^-1(0.58333)
Ø = 35.69 degree
At what height would an 15 foot ladder touch the building if both ladders form the same angle with the ground?
Using the same trigonometric ratios
SinØ = opposite/hypothenus
Sin 35.69 = opposite/ 15
Cross multiply
Opposite = 15 × sin 35.69
Opposite = 8.75 feet
Therefore, the ladder will touch the building if both ladders form the same angle with the ground at height 8.75 feet.
3) Valerie works at a local amusement park. She earns $9.80 per hour. She 20 points
also receives $10 for meals daily. Last Friday, Valerie earned $88.40.
Which equation can be used to determine how many hours Valerie
worked on Friday? *
a. 9.80h + 10 = 88.40
b. 88.40h + 9.80 = 10
c. 10h + 88.40 = 9.80
d. 10h + 9.80 = 88.40
===========================================================
Work Shown:
h = number of hours worked.9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).9.80h+10 = total amount of money earned after adding on the meal bonus.9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.--------------------
Extra info (optional section)
If you want to solve for h, then you could follow these steps.
9.80h+10 = 88.40
9.80h = 88.40-10 ... subtract 10 from both sides
9.80h = 78.40
h = 78.40/9.80 .... divide both sides by 9.80
h = 8
Valerie worked 8 hours on Friday.
As a check,
9.80h + 10 = 88.40
9.80*8 + 10 = 88.40
78.40 + 10 = 88.40
88.40 = 88.40
The answer is confirmed.

PLEASE HELP MY OUT Solve: -2X + 5 +4X + 9 = 3 (6 + 4X) -12X
Show your work
Answer:
x=2
Step-by-step explanation:
first we will distribute out everything
-2x +5 +4x+ 9 = 3(6 +4x)- 12x
(multiply 3 to both 6 and 4x)
-2x +5 +4x+ 9= 18 +12x -12x
then combine like variables on both sides
(add -2x and 4x and add 5 and 9, for the other side add 12x and -12x)
2x+14= 18
then isolate x
2x=4
x=2
and substitute x for 2 to double check
-2(2)+5+4(2)+9=3(6+4(2))-12(2)
18=18
therefore 2 is correct
