For what values of x is x2 + 2x = 24 true?–6 and –4
–4 and 6
4 and –6
6 and 4

Answers

Answer 1

Answer: you can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.

given: x^2+2x=24 (subtract 24 on both sides to get make it look like x^2+x+1)

x^2+2x-24=0 (now factor x^2+2x-24 out)

x^2+2x-24 --> (x-4)(x+6)

new equation: (x-4)(x+6)=0 (now make them both equl zero)

new equaions: x-4=0 x+6=0 (now solve for x for both)

x-4=0 x+6=0
x=4 x=-6
your answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into x^2+2x=24 to find the answer.

Answers

no. of FEMALES =4/5(no. of members in club)
in that
no. of females over 20 years old=1/3(no. of FEMALES)=1/3(4/5(no. of members in club))
=4/15(no. of members in club)
no. of females over 20 years old/no. of members in club=4/15

Write the standard equation of the circle with the given center that passes through the given point. Center (-2,6); point (-2,10)

Answers

The general form of the equation of a circle is given by:
(x-a)²+(y-b)²=r²
where:
(a,b) is the center
r is the radius
Given that the circle with center (-2,6) and cuts point (-2,10), the equation of the circle will be found as follows:
the radius of the circle will be:
r=√[(x-a)²+(y-b)²]
r=√[(-2-(-2))²+(10-6)²]
r=√[(-2+2)²+4²]
r=√[0+4²]
r=4 units
hence plugging the values to obtain the equation we get:
(x-(-2))²+(y-6)²=4²
simplifying we get:
(x+2)²+(y-6)²=4²

randy's garden 3 rows of carrots with 3 plants in each row. Next year he plans to plant 4 times the number of rows. How many plants will he have next year

Answers

Answer:

Currently, Randy has 3 rows of carrots with 3 plants in each row, which gives a total of 3 * 3 = 9 plants.

Next year, Randy plans to plant 4 times the number of rows. Therefore, he will have 4 * 3 = 12 rows of carrots.

If each row still has 3 plants, then next year Randy will have a total of 12 * 3 = 36 plants.

Answer: 36 plants

Step-by-step explanation: 4 times the amount of rows is 12 (4x3) and 12 x 3 (amount of plants in each row) is equal to 36 plants

Answer:

Step-by-step explanation:

Answer: No Solution.

Step-by-step explanation:

So remember that you first need to solve for the parenthesizes, as it is the thing you need to do first in the order of operations: PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)

So, what you should do first is distribute the 3 into x - 1 as well as the 2 on the right side into 2x + 3.

7x-3(x-1) = 2(2x+3)

7x - 3x - 3 = 4x + 6

Then what you should do next is combine like terms on the left side, which is 7x & -3x.

So what you would get after combining like terms is:

4x - 3 = 4x + 6

Then what you should do next, is move the 4x from the right side to the left. In order to do that, you must subtract 4x by 4x on the right side, which would cancel it out.

And remember, what you do on one side, you do to the other.

So in the end, you should end up with this:

-3 = 6

Now, due to how there is no more x you are solving for, it would be no solution.
