The equivalent expression to 2x² + 4 + 3x² + 2x + 7 is 8x² + 2x + 11.
What is equivalent equation?An equivalent equation is an equation that has the same solution set as another equation. It is a mathematical expression that is equal in value to another expression. The two equations can often be solved using the same methods and yield the same result. Equivalent equations are useful in solving complex mathematical problems by breaking them down into simpler equations.
This is obtained by combining the like terms such as 2x² and 3x², which results in 5x², and 4 and 7 resulting in 11. The expression can be written as 5x² + 2x + 11. The final result can be obtained by multiplying 5x² with 2, which results in 8x². Hence, the equivalent expression is 8x² + 2x + 11.

find the slope (-2,5) and (1,-4)
Answer:
m=-3 (the answer should be have a negative sign.)Step-by-step explanation:
Slope is a surface with one end higher than the other and without no steps. It proceed at an angle.
First, you have to use the slope formula.
Slope formula:
[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}}[/tex]
Y₂= (-4)
Y₁=5
X₂=1
X₁=(-2)
Solve.
[tex]M=\dfrac{-4-5}{1-(-2)}[/tex]
(-4)-5=(-9)
1-(-2)=1+2=3
(-9)/3=(-3)
Therefore, the slope is -3, which is our answer.

The owner offers a payment plan where the total cost of the
mountain bike is paid in 3 equal monthly payments. Determine the amount
of each monthly payment.
Answer:
$131.85
Step-by-step explanation:
First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.
For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.
You're paying over 3 months time, so to find payment each month just divide by 3.
395.539/3 = 131.8463333
Round to 131.85
Your answer is $131.85 dollars per month

In GHI the measure angle I = 90° the measure of angle G = 5° and IG = 57 feet. Find the length of GH to the nearest tenth of a foot
Answer:
GH = 57.2 feet
Step-by-step explanation:
Given the following
m<I = 90 degrees
<G = 5 degrees
IG = 57 feet
Required
Length of GH
According to the data given
GH is the hypotenuse
iG is the adjacent side to m<G
Cos theta = adj/hyp
Cos 5 = IG/GH
Cos 5 = 57/GH
GH = 57/cos 5
GH = 57/0.9962
GH = 57.2 feet

([tex]12[/tex]) pastries in one hour.
Step-by-step explanation:
This problem involved the concept of rates. A rate is a way of expressing the amount of work done compared to the amount of time it took, to find the pace at which one does the work. To express a rate, the general format used is: ([tex]work:time[/tex])
Substitute in the given values:
[tex]30:2.5[/tex]
In the problem, one is asked to find how many pastries can be made in one hour. To find this value, divide the rate by (2.5). This will leave (1) on the time side, and the amount of work done on the (work) side.
[tex]30:2.5[/tex]

Hamburger Heaven is having a lunch special where customers buy one 1/4 pound cheeseburger and get one free. If they set aside 114 2/3 pounds of meat, how many -pound cheeseburgers can they make?
Answer: 459 cheeseburgers
Step-by-step explanation:
To find out the number of cheeseburgers that can be made, divide the amount of meat set aside by the amount of meat it takes to make one cheeseburger.
The amount of meat they have is:
= 114²/₃
= 344/3
Number of cheeseburgers is:
= 344/3 ÷ 1/4
= 344/3 * 4/1
= 1,376 / 3
= 458.67
= 459 cheeseburgers
