can you help me solve this (x+5)(x+3)=0
Answer:
x= -3, x=-5
Step-by-step explanation:
Answer:
x = -3 or -5
Step-by-step explanation:
This is a quadratic equation, meaning that the solutions (x-values) will occur when the parabola intersects the x-axis
For now, all you have to do is isolate each mini expression, because you can divide each side by either parenthesis (since it's multiplication)
(x+5)(x+3) = 0 (x+5)(x+3) = 0
divide by (x+5) divide by (x+3)
x+3 = 0 x+5 = 0
subtract 3 subtract 5
x = -3 x = -5
Keep in mind that the parabola intersects the axis at BOTH (-3, 0) and (-5, 0)
Therefore, both answers (must be together unless question says otherwise) can be the value of x
x = -3 OR -5
Claire bought five toy boxes. Each toy box is in the shape of a cube. The total volume of the five toy boxes when placed in a row is 2,600 cubic inches. Claire thinks she will need about 40 inches of floor length for the toy boxes and Lucy thinks she will need about 45 inches of floor length for the toy boxes.
Answer:
Please find the answer in the explanation.
Step-by-step explanation:
Given that Each toy box is in the shape of a cube. The total volume of the five toy boxes when placed in a row is 2,600 cubic inches.
If Claire thinks she will need about 40 inches of floor length for the toy boxes and Lucy thinks she will need about 45 inches of floor length for the toy boxes, one of them must be right.
Since Volume = L × B × h
Substitute the volume value and the length into the formula to know the area of the box. This must be in whole number and not in decimal number.
Area = 2600 / 40
Area = 65 square inches. For Claire.
Then for Lucy, we get:
Area = 2600 / 45
Area = 57.7778 square inches
We can therefore conclude that Claire is correct.

Factor by grouping
3x^2-11x+10
Answer: (x - 2)(3x - 5)
Step-by-step explanation:
I'm using the berry method to factor, so first, I multiply 3 times 10 to get 30. Now I have to figure out what two numbers, when multiplied together, yield 30 and when are added together, give me -11. Those two numbers are -6 and -5. The equation now becomes (3x -6)(3x -5). Reducing the first binomial: (3x - 6)/3 = (x - 2)
the solution is (x - 2)(3x - 5), and we can check this by multiplying it out, which gives us our starting number, meaning it's correct.

Step-by-step explanation:
first, add one to each side to eliminate the negative one. you'll get:
7= [tex]\frac{1}{4}[/tex]z
now, to get rid of the 1/4, multiply both sides by 4.
(7x4)=(1/4z)4

the jones family road trip covers 3640 miles and they visit 9 states. what is the average mileage per state?
Answer:
About 404.4444444445
Step-by-step explanation:
Answer:
404 miles per state
Step-by-step explanation:
First, let's write an equation.
For every 9 states, they covered 3640 miles. So our equation would look like this:
9s=3640 (s= number of states)
Second, let's get s by itself. To do this, divide 9 on both sides/

If josiah skateboards from his house to school 4 miles away. It takes him 20 minutes.
If josiahs speed, in miles per minute, is constant, what is the constant of proportionality?
The constant of proportionality is 0.2
The constant of proportionality for Josiah's speed is 0.2 miles per minute.
To find the constant of proportionality, we can use the formula:
constant of proportionality = distance / time
In this case, we have the distance Josiah skateboards from his house to school is 4 miles, and it takes him 20 minutes.
So, the constant of proportionality is:
4 miles / 20 minutes = 0.2 miles/minute
Therefore, the constant of proportionality for Josiah's speed is 0.2 miles per minute. This means that he skateboards at a constant rate of 0.2 miles per minute from his house to school.

Answer:
15
Step-by-step explanation:
First, you must distribute 5 to (x + 3)
5(x + 3) - 5x
5x + 15 - 5x
5x - 5x +15
(You can typically say 0x + 15, as a representation to show there are no more x values, but it is bet not to show any if there are none left)
(5x - 5x will cancel out, leaving only 15)

Given ∠A and ∠B are vertical angles with m∠A=10x+5 and m∠B=15x−10 .
What is x?
Enter your answer in the box.
The measure of x is 1.
What are vertical angles?Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.
given:
m∠A=10x+5 and m∠B=15x−10 .
As, ∠A and ∠B are vertical angles
so,
m∠A= m∠B
10x +5 = 15x -10
10x - 15x = -10 +5
-5x = -5
x= 1
Hence, the value of x is 1.
