Answer:
[tex] 3 {x}^{2} + 12x + 5[/tex]
Step-by-step explanation:
[tex](x^2 + 3x) + (2x^2 + 9x + 5) \\ \\ = x^2 + 3x + 2x^2 + 9x + 5 \\ \\ = {x}^{2} + 2 {x}^{2} + 3x + 9x + 5 \\ \\ = 3 {x}^{2} + 12x + 5[/tex]

Simon set up his tent in his backyard last night. His tent is 6 feet tall. To secure it to the ground, he attached a rope from the top of the tent to the ground 8 feet away from the bottom of the tent as shown below. How many feet long, R, is the rope?
Length of Simon's tent = 6 feet
Distance from the bottom of the tent to the tent's base = 8 feet
Let the length of rope be R.
The tent and the rope forms a right angle triangle where the rope is the hypotenuse.
We know that :
[tex]\color{hotpink} \tt{hypotenuse}^{2} \color{plum}= {base}^{2} + {height}^{2} [/tex]
Which means :
[tex] = \tt {R}^{2} = {6}^{2} + {8}^{2} [/tex]
[tex] =\tt {R}^{2} = 36 + 64[/tex]
[tex] = \tt {R}^{2} = 100[/tex]
[tex] =\tt R = \sqrt{100} [/tex]
[tex]\hookrightarrow\color{plum}\tt \bold{R = 10 \: feet}[/tex]
Thus, the hypotenuse of this triangle = 10 feet
▪︎Therefore, the length of the rope = 10 feet

A new bank customer with $4,000 wants to open a money market account. The bank is offering a simple interest rate of 1.2%.
a. How much interest will the customer earn in 30 years?
b. What will the account balance be after 30 years?
Answer:
Interest: $1440
Total Account Balance: $5440
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.2%/100 = 0.012 per year,
then, solving our equation
I = 4000 × 0.012 × 30 = 1440
I = $ 1,440.00
The simple interest accumulated
on a principal of $ 4,000.00
at a rate of 1.2% per year
for 30 years is $ 1,440.00.
The simple Interest is $1440 and the total Account Balance: $5440.
What is simple interest?Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.
First, converting R percent to r a decimal,
r = R/100 = 1.2%/100 = 0.012 per year,
Then, solving our equation,
I = 4000 × 0.012 × 30 = 1440
I = $ 1,440.00
The simple interest accumulated,
on a principal of $ 4,000.00
at a rate of 1.2% per year
for 30 years is $ 1,440.00.
Therefore, the simple Interest is $1440, and the total Account Balance: $5440.

Answer:
b
Step-by-step explanation:
to solve for m, you need to leave the m by itself.
since 14(1/6) on the m side, it needs to be eliminated. To do that, you need to subtract 14(1/6) on both sides. Therefore, the answer is B.
Does (0, 0) make the equation y = 9x − 5 true?
Answer:
no
Step-by-step explanation:
y = 9x − 5
The point (0,0) means x=0 and y=0
Substitute this into the equation and see it is true
0 = 9*0 -5
0 = 0-5
0 = -5
This is not true so the point is not a solution.
