Answer:
(3x - 3)(x + 2)
Step-by-step explanation:
3x^2 + 3x - 6
(3x^2 + 6x)(-3x - 6)
3x(x + 2) -3(x + 2)
(3x - 3)(x + 2)
Solve [X + 8) = 5
With steps
Answer:
X=(-3)
Step-by-step explanation:
1.Subtract 8 from both sides of the equation.-(x+0)=5-8-the 0 is there because the 8 on the left side is canceled out.
2.5-8 is all you have to look at.-when you look at this you know that it will be negative because 8 is on the right of the minus sign and it is greater than 5.
3.Use a calculator or you fingers to find answer.-(4,3,2,1,0,-1,-2,-3)

Michelle is making a poster for a class presentation. She plans to have four sections of information, each with a different background color. The diagram shows the lengths and widths of each section, where a is the length of the red section. Which expression for the area of the poster is written as the sum of the areas of each colored section? (answer choices are in the screenshot provided. thanks! <3)
Answer:
first option
Step-by-step explanation:
the area of a rectangle is
base*height
[tex]Purple=(3)\times(a)\\\\=3a\\\\\\Green=(\frac{1}{2})\times(3)\\\\=\frac{3}{2}\\\\\\Red=1\times a\\\\=a\\\\\\Yellow=\frac{1}{2}\times 1\\\\=\frac{1}{2}[/tex]
so the sum is
[tex]\Sigma A=3a+a+\frac{3}{2}+\frac{1}{2}[/tex]
which is the first option
The expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2
Area of a rectangle = length × width
Purple color:
Area = length × width
= 3 × a
= 3a
Red color:
Area = length × width
= 1 × a
= a
Green color:
Area = length × width
= 3 × 1/2
= 3 1/2
Yellow color:
Area = length × width
= 1 × 1/2
= 1/2
Sum of the areas = purple + red + green + yellow
= 3a + a + 3 1/2 + 1/2
Therefore, expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2

Olly took a taxi 12 miles and paid $8.40. The cab driver charges $0.45 per mile after a flat fee. How much would it cost if Olly needed to take the taxi for 25 miles?
Answer:
$14.25
Step-by-step explanation:
12 x 0.45 = 5.4
8.40-5.40=3
3 is the flat fee
3+(0.45 x 25) = 14.25
Answer:
$14.25
Step-by-step explanation:
8.40 = .45(12) + b
8.40 = 5.4 + b
b = 3
b = .45(25) + 3
b = 11.25 + 3
b = 14.25

5-(x-6)=-7+3(-x+2)
Answer:
x=-6
Step-by-step explanation:
For this equation, when we remove the parenthesis, we get 5-x+6=-7+-3x+6.
Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.
The annual profit at a chain of stores is normally distributed with a mean of $61,000 and a standard
deviation of $23,000. The stores in the top 5% of annual profit were rewarded with a celebration. What
was the annual profit required to have a party?
Answer: $98,835.
Step-by-step explanation:
Given: Annual profit at a chain of stores is normally distributed with a mean ([tex]\mu[/tex]) of $61,000 and a standard deviation([tex]\sigma[/tex]) of $23,000.
Let [tex]x[/tex] denoted the profit.
Let [tex]x_0[/tex] be the minimum profit required to have a party.
The stores in the top 5% (i.e. 0.05) of annual profit were rewarded with a celebration.
i.e. [tex]P(x>x_0)=0.05[/tex]
[tex]\Rightarrow\ P(\dfrac{x-\mu}{\sigma}>\dfrac{x_0-61000}{23000})=0.05\\\\\Rightarrow\ P(z>\dfrac{x_0-61000}{23000})=0.05\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\\Rightarrow\ \dfrac{x_0-61000}{23000}=1.645\ \ [\text{critical z-value for p-value 0.05=1.645}]\\\\\Rightarrow\ x_0-61000 =1.645\times 23000\\\\\Rightarrow\ x_0-61000 =37835\\\\\Rightarrow\ x_0=37835+61000\\\\\Rightarrow\ x_0=98835[/tex]
Hence, the annual profit required to have a party was $98,835.
What strategy would be the best to solve this problem? Ann-Marie bought apples. She kept one-third for herself and gave the rest to 4 friends. Each friend got 2 apples. How many apples did Ann-Marie buy? A. guess, check and revise B. work backwards C. use a formula D. look for patterns
Answer:
D. Look for patterns
Step-by-step explanation:
To solve :
Assume number of apples bought = x
Fraction kept = 1/3 of x
Fraction shared = (x - x/3) = (3x - x) /3 = 2x/3
Number of people who shared (2x/3) = 4 with each getting 2
Total number shared = 4 * 2 = 8
Fraction shared = total shared
2x/3 = 8
Multiply both sides by 3
(2x/3) * 3 = 8 * 3
2x = 24
x = 12
Hence, Anne-Marie purchased 12 apples
