Answers
Answer:
3n²+3n-60
Step-by-step explanation:
Area of rectangle= L*W
A=3(n-1)(n+2)
A=3(n²+n-2)
A=3n²+3n-6
54=3n²+3n-6
3n²+3n-6-54=0
3n²+3n-60=0
Answer:
3, 3, - 60
Step-by-step explanation:
Area = lw
Therefore 54=(3n-3)(n+2)
Expand and we get:
3n^2+6n-3n - 6=54
Combine terms and move 54 to left side:
3n^2+3n-60

Find the surface area of the triangular prism
Answers
Answer:
169 cm^2
Step-by-step explanation:
Right surface (rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Left surface (hidden rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Bottom surface (hidden rectangle)
A = LW = 9 cm * 5 cm = 45 cm^2
Front face = back face = 2 * triangle
A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2
total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2

You have $55 in your bank account, and you would like to buy a new phone for $395. You can save $5 for each hour you work. How many hours must you work to buy it?
Answers
Answer:
(At least) 68 hours
Step-by-step explanation:
So we already have $55 in our bank account.
And we earn $5 per hour.
In other words, the total amount of money in our account after working x hours is represented by the equation:
[tex]y=5x+55[/tex]
We want to buy a new phone that costs $395. To find out how many hours we need to work, substitute 395 for y. Thus:
[tex]395=5x+55[/tex]
Subtract 55 from both sides:
[tex]340=5x[/tex]
Divide both sides by 5:
[tex]x=68[/tex]
Therefore, we must work for (at least) another 68 hours in order to earn enough money to purchase the phone.

~AnonymousHelper18079x-6y=-20 through (0,-4)
Answers
To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.
9x - 6y = 20
-6y = 20 - 9x
y = -20/6 - (-9/6x)
y = 9/6x - 20/6
y = 3/2x - 10/3
To make the perpendicular line, take the slope and apply the opposite and reciprocal.
y = -2/3x - 10/3

3.5 + 1.2(6.3-7x) =9.38
Answers
Answer:
x = 0.2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
3.5 + 1.2(6.3 - 7x) = 9.38
Step 2: Parenthesis (distribute)
3.5 + 7.56 - 8.4x = 9.38
Step 3: Combine like terms (constants)
11.06 - 8.4x = 9.38
Step 4: Subtract 11.06 on both sides
-8.4x = -1.68
Step 5: Divide both sides by -8.4
x = 0.2

Carina begins to solve the equation Negative 4 minus two-thirds x equals negative 6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Select three options. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 2. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 10. The equation can be solved for using exactly one more step by multiplying both sides by Negative three-halves. The equation can be solved for x using exactly one more step by dividing both sides by Negative two-thirds. The equation can be solved for x using exactly one more step by multiplying both sides by Negative two-thirds.

Answer:
options 3 and 4 are correct
Step-by-step explanation:
And form the remainder of the problem, you isolate x by just multiplying by the negative reciprocal, which is -3/2, or just dividing by the number in front off x, which is -2/3, which makes statements three and four true. so this makes this three and four options

What is a linear equation?A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.
Given here -4-2/3x +4=-6+4
⇒-2/3x = -2
⇒ -2/3x ×3/2 = -2 ×3/2
⇒ x = 3
Hence the final answer is 3.
