Answer:
5x² - 5x + 17
Step-by-step explanation:
(3x² + 7) + (2x² - 5x + 10)
Combine the like terms.
3x² + 2x² = 5x²
-5x does not have a like term, so there is no change.
7 + 10 = 17
Combine them, and the final equation is
5x² - 5x + 17.
Answer: 5x² - 5x + 17
Step-by-step explanation:
(3x^2+7)+(2x^2-5x+10)
3x^2 + 2x^2
-5x
7 + 10
5x^2 - 5x + 17

2x[tex]2x^{2}-3x-5[/tex]
Answer:
2x²-3x-5
=2x²-3x-5
=2x²-5x+2x-5
=2x(x-5)+2(x-5)
=(x-5)(2x+2)
Answer:
(x + 1)(2x - 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2x² - 3x - 5
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 5 = - 10 and sum = - 3
The factors are + 2 and - 5
Use these factors to split the x- term
2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )
= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term
= (x + 1)(2x - 5) ← in factored form
Running at a constant rate, Miguel ran 12 miles in a time of 120 minutes. How many minutes does it take Miguel to run 6 miles?
Answer:
20
Step-by-step explanation:
120/6
Answer:
60 minutes
Step-by-step explanation:
First, lets write the problem into an equation
12 miles/120 minutes = 6 miles/x minutes
Then, we solve
12/120 = 6/x
12x = 720
x = 60
Therefore, your answer is 60 minutes

A gardening store ordered 5,710 potted plants last year. This year, the store ordered 10% fewer potted plants. How many potted plants were ordered this year?
Answer:
5319
Step-by-step explanation:
There are two ways that the answer can be determined
Method 1
Determine 10% of 5710. the answer gotten is subtracted from 57100.1 x 5710 = 571
5710 - 571 = 5319
Method 2
If the plants planted this year are 10% fewer, the plants this year are (100% - 10%) 90% of last year's plant
90% x 5710
0.9 x 5710 = 5319

Luis has some nickels, dimes, and quarters. The value of all of the coins, in cents, is represented with the expression shown.
5(2 + 2) + 10x + 25 (3x + 1)
Which part of the expression represents the number of quarters that Luis has?
A. x+2
B. 10x
C. 3x+1
D. 25(3x+1)
B.
10.
C
3.2 +1
D.
25 (3x + 1)
Answer:
The part of the expression that represents the number of quarters is;
D. 25·(3·x + 1)
Step-by-step explanation:
From the question, we have;
The values of the coins Luis has = Nickels, Dimes and quarters
The expression that represents the value of all the coins in cents is given as follows;
5(x + 2) + 10·1 + 25·(3·x + 1)
The value of a nickel = 5 cents
The value of a dime = 10 cents
The value of a quarter = 25 cents
Therefore, the part of the expression representing the number of quarters Luis has, has 25 as a factor
Therefore, the part of the expression that represents the number of quarters = 25·(3·x + 1).
Write an equation in slope-intercept form of the line shown. (8, 4) (4, 1)
Step-by-step explanation:

y-1 = 3/4x -3
y = 3/4x -2
The perimeter of the triangle is 29 cm.
a. Write an equation and solve for x.
b. Use the value of x to find the lengths of the sides of the triangle.
c. What kind of triangle is this: scalene, isosceles, or equilateral? Explain how you know using the calculated side lengths, not the picture
2x+2
3x - 1
x + 4
Answer:
Step-by-step explanation:
Equation
2x + 2 + 3x - 1 + x +4 = 29 Collect like terms on the left
6x + 5 = 29 Subtract 5 from both sides
6x = 29 - 5
6x = 24 Divide by 6
x = 24/6
x = 4
Length of the Sides.
2x + 2 = 2*4+2 = 10
3x - 1 = 3*4 - 1 = 12 - 1 = 11
x + 4 = 4 + 4 = 8
Type of Triangle
Scalene.

Answer:
D. [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Step-by-step explanation:
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex] = [tex]\sqrt[4]{\frac{3x^2}{16y^4}}[/tex] = [tex]\sqrt[4]{\frac{3x^2}{(2y)^4}}[/tex] = [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Correct choice is D
[tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex] is the simplification of the given expression.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are called PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
It is given an expression [tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex]
Simplifying the given expression using the PEMDAS technique,
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }\\\\\sqrt[4]{\frac{3x^2}{16y^4} }\\\\\frac{\sqrt[4]{3x^2}}{2y}[/tex]
Therefore, the simplified value of the given expression is [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]. Thus, the option D is correct.

If there are 60 seconds in an minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week? Hint: Use a calculator to solve this problem.James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
Answer:
Part a) 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week
60x60=3600 x 24= 86400 x 7= 604800
So 604,800 seconds in a week
Part b) James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
So 3 x 1= $3
+ $2
2 x 2= $4
3+2+4= $9
10-9= $1
So they'll get back $1

Answer:
I) 616
II) 4.53
Step-by-step explanation:
For the first one, just plug in 7 as R.
A = 4 x (22/7) x 7^2
A = 12.57142857 x 49
A = 616
For the second, one, put 452 4/7 as A.
452 4/7 also is 258.285
258.285 = 4 x (22/7) x r^2
258.285 = 12.57142857 x r^2
Divide both sides by 12.57142857
20.55372408 = r^2
Square root 20.55372408 for R.
4.533621519 = R

4.53 = R
