x = 25 and x = –25
x = 125 and x = –125
no real solution

Answers

Answer 1
Answer:

For this case we have the following polynomial:

We can solve the polynomial by factoring.

We have then:

From here, we clear the solutions of the equation.

Solution 1:

Solution 2:

Answer:

the solutions to the quadratic equation x ^ 2 - 25 = 0 are:

x = 5 and x = -5
Answer 2
Answer: If you would like to find the solutions to the quadratic equation x^2 - 25 = 0, you can do this using the following steps:

x^2 - 25 = 0
(x + 5) * (x - 5) = 0
x^2 - 5x + 5x - 25 = 0
1. x = - 5
2. x = 5

The correct result would be x = 5 and x = –5.

Answers

Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4  cups of sugar, so there is 3/4 cup of flour for each cup of gallons of water.”How many cups of disinfectant are needed for 20 gallons of water so c is 
I use ratio and proportionchanges 3/4= .75.75 cups/2 gallons= x cups/2o gallonscross multiply2x= 15x= 7 1/2 cupsalso there are 10 gallons for every 3/4 cup10 x 3/4= 30/4= 7 1/2I like ratio and proportion it's more consistent in solving lots of problemshope this helps

H(t)=-16t^2+24So I have to find how long (in seconds) it will take a tool to fall to the ground from a height of 24 feet. I am using the equation h(t)=-16t^2+24 to find it but I'm not sure how to solve it or where to even get started! Any help would be great thank you!

Answers

when h(t)=0, it hits the ground

solve
0=-16t^2+24
factor out -8
0=-8(2t^2-3)
we know that
0=2t^2-3 since factors have to multiply to 0
add 3 to both sides
3=2t^2
divide both sides by 2
1.5=t^2
sqrt both sides
1.2247=t

after about 1.2247 seconds it will hit the ground

Hello,

Let y the smaller
x the greater
x+2y=98 ==>x+2y=98 (1)
x=3y-22 ==> x-3y=-22 (2)
