How do you solve for x in x^2+5x=36

Answers

First we want to set the equation equal to zero by subtracting 36 from each side...

x^2 + 5x -36 = 0

Now we factor

(x + 9)(x - 4) = 0

Now set each expression equal to zero and solve...

x + 9 = 0              x - 4 = 0
x = -9                    x = 4

Your solution set is

(-9, 4)

Answer: (-9,4)

Step-by-step explanation: First, we set the equation equal to zero by subtracting 36 from both sides to get x² + 5x - 36 = 0.

Next, we factor the left side of the equation

as the product of two binomials.

Since the factors of -36 that add to +5 are +9 and -4,

we have (x + 9)(x - 4) = 0.

This means that either x + 9 = 0 or x - 4 = 0.

Solving each equation from here,

we have x = -9 or x = +4.

So your solution set is (-9,4).

James says that 5/5 is greater than 9/10 is he correct please explain so that it is not confusing

Answers

Yes, James is correct. 

Think of a pizza. If there are 5 slices and you have all 5 of them, then you have the whole pizza. 

Now, instead of the pizza having 5 slices, it now has 10. Since the pizza is still the same size, the pieces are going to smaller. If you have 9 slices out of the 10, you won't have the whole pizza.

This is why 5/5 is greater than 9/10.

What is greater than 6200 feet or one mile and 900 feet

Answers

One mile is 5280 feet, so when you add 900 to that, it ends up being 6180 feet, so 6200 feet is greater.

We should convert either of them to have the same unit to compare.

1 mile = 5280 feet 

Add 1 mile (in feet) to 900 feet.
5280 + 900 = 6180 feet

6200 feet > 6180 feet

6200 feet is greater

Question #1:
Since it is unknown how much they paid for the original painting, we'll use x to represent that. 2x+1000 is equal to 55,000, so that is our equation.
2x+1000=55,000
2x=54,000
x=27,000 
The Leungs originally paid $27,000 (answer choice B)

Question #12:
-4(x-11)=16
Apply the distributive property. 
-4x+44=16
-4x=--28
x=7
Since x=7, let's figure out which answer choice can be possible by subsituting the x in each answer choice with 7.
Answer choice F: Does 7-11=4? No, so this answer can't be correct.
Answer choice G: Does 7-11=-4? Yes! This answer is correct.
Answer choice H: Does -28-11=16? No, so this answer can't be correct.
Answer choice I: Does -28+44=64? No, so this answer can't be correct.
It is answer choice G.
