To express (x+6)(3x-2) as a trinomial, we expand the brackets
(x + 6) (3x - 2)
x (3x - 2) + 6 (3x - 2)
3x² - 2x + 18x - 12
3x² + 16x - 12
Therefore, (x + 6) (3x - 2) as a trinomial is 3x² + 16x - 12

Answer:
∠AMC = 76°
Step-by-step explanation:
1) Because ∠YMC = 170°, you need to add 5x+19 (∠YMA) and 5x+1 (∠AMC) to equal the length of ∠YMC:
170 = 5x + 19 + 5x + 1
2) Combine like terms:
170 = 10x + 20
3) Subtract 20 from both sides:
150 = 10x
4) Divide by 10:
x =15
5) Replace x in ∠AMC with 15:
5(15) + 1
6) Multiply:
∠AMC = 76°
The measure of ∠AMC is 76°.
Given that, m∠YMC=170°, m∠YMA=(5x+19)° and m∠AMC=(5x+1)°.
We need to find the value of m∠AMC.
What are adjacent angles?The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be complementary angles or supplementary angles when they share the common vertex and side.
Now, m∠YMA+m∠AMC=m∠YMC
⇒(5x+19)° + (5x+1)°=170°
⇒10x+20=170
⇒10x=150
⇒x=15
So, m∠AMC=5x+1=76°
Therefore, the measure of ∠AMC is 76°.

Solve 1.3 - 5g = 7.4 Show all work and check the solution
Answer:
1.22
Step-by-step explanation:
Subtract 1.3 from each side, so it now looks like this: 5g = 6.1Divide each side by 5, so it now looks like this: g = 1.22I hope this helps!
Answer:
The value of 'g' in the equation is -1.22.
Step-by-step explanation:
Solving this problem entails of isolating the variable 'g.' To start this process, we must use the subtraction property of equality. We will subtract 1.3 from both sides of the equation.
1.3 - 5g = 7.4
1.3 - 1.3 - 5g = 7.4 - 1.3
-5g = 6.1
You can see that we have gotten one step closer to getting the variable alone. Now we will use the division property of equality. To do this, divide both sides of the equation by negative five.
-5g = 6.1
-5g / -5 = 6.1 / -5
g = -1.22
The variable has finally been isolated. The value of 'g' is -1.22.
1) Given the area of a Football field (57,600 sqft), and the dimensions of a
Basketball court(84ft x 50ft), what fraction of the football crowd would fit
on the court?"
Set up a ratio. Basketball / Football (Area)
a half (1/2)
a quarter (1/4)
a tenth (1/10)
or less than a tenth (< 1/10)
Answer:
Option (d).
Step-by-step explanation:
Given that,
The area of a Football field is 57,600 sqft
The dimensions of Basketball court is 84ft x 50ft
We need to find what fraction of the football crowd would fit on the court. Taking ratio of the area of basket ball court to the football court as follows :
[tex]R=\dfrac{84\times 50}{57,600}\\\\R=\dfrac{7}{96}\ =\ 0.0729[/tex]
It is less than a tenth. Hence, the correct option is (d).

Dan had $105 to spend on 8 books. After buying them he had $17. How much did each book
cost?
Answer:
each book cost $11
Step-by-step explanation:
$105 - $17 = $88
$88 / $8 = $11
Hope this helps and can you please mark me brainliest? I just need 4 more brainliest to become expert
Answer:
$11
Step-by-step explanation:
So in order to calculate the amount of money each book cost, we want to first find the exact number all 8 books cost. We know that Dan has 17 dollars left from the total 105 so we should subtract 17 from 105 to find out the total cost:
$105 - $17 = $88
Now we can divide the total cost by 8 because we want to find the unit price or the price of 1 book:
$88 / 8 = $11
From the equation above, we found out that the unit price is $11. :)

An athletic club buys car magnets and pom-poms for club members. The car magnets cost 4.95 each, and pom-poms cost each. The athletic club spends a total 580 of before tax, on a total of $300$ items. Each club member should receive $1$ car magnet and $2$ pom-poms. If $x$ represents the number of car magnets, and $y$
Answer:
Each car magnet costs $4.95 and each pom-pom costs $0.425
The club spent $495 on 100 car magnets and $85 on 200 pom-poms.
Step-by-step explanation:
I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.
x + y = 300
2x = y (now we replace y)
x + 2x = 300
3x = 300
x = 100
The club purchased 100 car magnets and 200 pom-poms.
To determine the price of each pom-pom:
($4.95 x 100) + 200P = $580
$495 + 200P = $580
200P = $85
P = $0.425

Four less than 3 times a number is no less than five added to 2 times the same number.
Answer:
the number is no less than 9
Step-by-step explanation:
4 less than 3 times a number can be expressed as ...
3n -4
5 added to 2 times the same number can be expressed as ...
2n +5
The "is no less than" relationship can be expressed as "greater than or equal to".
3n -4 ≥ 2n +5
n ≥ 9 . . . . . . . . . add 4-2n to both sides
The number is no less than 9.
x – 3y = 15 and y = -3x + 4
Determine whether the lines are parallel, perpendicular or neither
Show your work
The equation of lines x - 3y = 15 and y = -3x + 4 are perpendicular lines since the product of their slopes is -1
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line A be represented as
x - 3y = 15
Adding 3y on both sides of the equation , we get
3y + 15 = x
Subtracting 15 on both sides of the equation , we get
3y = x - 15
Divide by 3 on both sides of the equation , we get
y = ( 1/3 )x - 5 be equation (1)
Now , it is of the form y = mx + b where m is the slope and b is the y-intercept
So , slope of line A = 1/3
And ,
The equation of line B is y = -3x + 4
Now , it is of the form y = mx + b where m is the slope and b is the y-intercept
So , slope of line B = -3
Now , the product of the slopes = -1 , means the lines are perpendicular
So , ( 1/3 ) x -3 = -1
-1 = -1
Hence , the lines are perpendicular

Choice C. is equivalent.
Let's first simplify, starting with the denominator.
a to the power of 0 is 1. —> any value to the power of 0 is 1.
That leaves us with (1b^2)^4. Now we can distribute the exponent. But before that, let's get rid of the coefficient 1, which isn't necessary.
Now we are left with (b^2)^4.
Let's use the power of the power rule, which means that we multiply the exponent by the exponent. The denominator is now b^8.
Looking at the numerator, there is a b, which has a hidden exponent of one. —> We can get rid of it by taking away its exponent of 1 with the b^8 from the denomiator.
. . . b^1 goes away, and b^8 becomes b^7.
We cannot simplify any further, therefore the final expression is. . .
