To find GCF we need to find what these expressions have in common
30x²=5*3*2x²
45x⁵=5*3*3x²x³
Now we can see, that GCF=5*3*x² = 15x²
Answer :
15x²
Step-by-step explanation:
[tex]30x^{2}=2\times \left( 15x^{2}\right) \\45x^{5}=3x^{3}\times \left( 15x^{2}\right)[/tex]

The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.
What is an Equation in Vertex Form?The vertex form of an equation is expressed as, y = a(x - h)² + k, where:
(h, k) = vertex of the parabola.
Given the equation, y = -6x² + 3x + 2, factor the equation:
y = -6(x² - 0.5x) + 2
y = -6(x² - 0.5 + 0.0625) + 2.375
Rewriting the equation as perfect squares, we would have:
y = -6(x - 0.25)² + 2.375
The vertex form of y = -6x² + 3x + 2 is, y = -6(x - 0.25)² + 2.375.

Gabrielle and Rob each earn $22 an hour, and each works 40 hours this week. Rob spends 1/2 of his earnings this week on bills and then buys a video game for $25. 75. How much of his earnings fro
The amount spent is an illustration of subtraction and proportions
The amount left in his earnings is $414.25
How to determine the amount left in his earnings?The given parameters are:
Rate = $22 per hour
Time = 40 hours
So, the total earnings is:
Total = $22 * 40
Evaluate
Total = $880
He spent half on bills.
So, we have:
Bills = 0.5 * $880
Bills = $440
He buys a video game for $25.75
So, the amount left is
Amount left = $880 - $440 - $25.75
Amount left = $414.25
Hence, the amount left in his earnings is $414.25

Step-by-step explanation: that's the answer on edge.
The solution is, the minimum monthly payment is $221.93. Among the choices, the answer is D.
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
Solving for the future values of the credit card balances:
1260(1 + 0.12/12)^24
= 1599.8656571502122308900(1 + 0.18/12)^24

= 1649.0625893406018547
Adding the future balances to obtain total bill:
1599.8656571502122308 + 1286.5525307361225971 + 1543.3734529164803335 + 1649.0625893406018547
= 6078.85
Solving for the annuity A (monthly payments for each account):
1599.87 = A [(((1 + 0.12/12)^24) - 1) / (0.12/12)] A = 59.31
1286.55 = A [(((1 + 0.18/12)^24) - 1) / (0.18/12)]A = 44.93
1543.37 = A [(((1 + 0.09/12)^24) - 1) / (0.09/12)]A = 58.93
1649.06 = A [(((1 + 0.16/12)^24) - 1) / (0.16/12)]A = 58.76
Adding the annuities together to obtain the minimum monthly payment:59.31 + 44.93 + 58.93 + 58.76 = 221.93

% compounded continuously. After 20 years, how much more money would Lincoln have in his account than Eli, to the nearest dollar?
Using compound interest and continuous compounding, it is found that Lincoln would have $15,856 more in his account than Eli.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.Hence, for Lincoln, we have that the parameters are as follows:
P = 49000, r = 0.06125, n = 365, t = 20.
Hence the amount will be of:
[tex]A_L(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A_L(20) = 49000\left(1 + \frac{0.06125}{365}\right)^{365 \times 20}[/tex]
[tex]A_L(20) = 166787[/tex]
What is continuous compounding?The amount is given by:
[tex]A(t) = Pe^{rt}[/tex]
For Eli, we have that r = 0.05625, hence the amount will be given by:
[tex]A(t) = Pe^{rt}[/tex]
[tex]A_E(20) = 49000e^{0.05625 \times 20} = 150931[/tex]
What is the difference?It is given by:
[tex]D = A_L(20) - A_E(20) = 166787 - 150931 = 15856[/tex]
Lincoln would have $15,856 more in his account than Eli.

10x - 22 + 3x + 20 = 180
13x - 2 = 180
13x = 182
x = 14
Answer:
m∠RQT=62°
m∠SQR=118°
Step-by-step explanation:
m∠SQT=m∠SQR+m∠RQT
180°=(10x-22°)+3x+20°
180°=13x-2°
180°+2°=13x
182°=13x
x=182÷13=14°
x=14°
So,
m∠RQT=3(14)+20°=62°
And,
m∠SQR=10(14)-22°=140°-22°
m∠SQR=118°

Remark
You have to convert one of the numbers. It doesn't matter which one, but you can't simply divide one into the other the way the numbers stand.
Conversion
20 kilograms = 20 * 1000 grams / kg
20 kilograms = 20000 grams
Formula
Number of books = mass of bookcase / mass of 1 book
Givens
number of books = ??
mass of bookcase = 20000 grams
mass of one book = 500 grams
Solution
number of books = 20000 / 500
number of books = 40
