Answer: 3x^2 +13x - 10
Step-by-step explanation:
(x+5)(3x-2) = x(3x-2) + 5(3x-2)
x(3x-2) + 5(3x-2) = 3x^2 - 2x + 15x - 10
3x^2 - 2x + 15x - 10 = 3x^2 + 13x - 10
Answer:
3x²+13x-10
Step-by-step explanation:
(x+5)(3x-2)x(3x-2)+5(3x-2)3x²-2x+15x-103x²+13x-10Someone pls help me I will make you brain

The Moon is about 240,000, or x _____ 10 miles from earth
Step-by-step explanation:
240,000 = 24 x 10^4
24 followed by 4 zeros = 24 x 104
Just make the number of zeroes be the exponent for 10
24 = 24 x 10^0
240 = 24 x 10^1
2400 = 24 x 10^2
24000 = 24 x 10^3
240,000 = 24 x 10^4 miles

what is the ratio to 8 adults and 24 students?
Answer:
8:24
8/24
3#
Step-by-step explanation:
mark as a brainlist
Answer:
8 : 24 = 1 : 3
Step-by-step explanation:
The ratio is not in lowest terms so we found an equivalent ratio by simplifying
We can simplify the ratio 8 : 24 by dividing both terms by the greatest common factor (GCF).
The GCF of 8 and 24 is 8.
Divide both terms by 8.
8 ÷ 8 = 1
24 ÷ 8 = 3
Therefore:
8 : 24 = 1 : 3

Which of the following does not represent a function?
Answer:
D or last oneStep-by-step explanation:
Verify the graphs by the vertical line test.
If a vertical line crosses the graph at two or more points, then it is not a function.
We can see the first 3 graphs pass the test but the last one fails.
So the last graph (bottom right picture) doesn't represent a function.

Solve the given equation.
- 29 = - 13 - n
Write step by step how you solved it.
Answer:
The answer is n=16
Step-by-step explanation:
Let's solve your equation step-by-step.
−29=−13−n
Step 1: Simplify both sides of the equation.
−29=−13−n
−29=−13+−n
−29=−n−13
Step 2: Flip the equation.
−n−13=−29
Step 3: Add 13 to both sides.
−n−13+13=−29+13
−n=−16
Step 4: Divide both sides by -1.
−n/−1 =−16/−1
n=16
On a map, 1 inch equals 15 miles. Two cities are 7 inches apart on the map. What is the actual
distance between the cities?
The actual distance between the cities is miles.
Answer:
105 miles
Step-by-step explanation:
The ratio you have is 1:15
So you must multiply 7 by 15 to find the actual distance in miles.
7*15=105

A tree company charges a delivery fee for each tree purchased in addition to the cost of the tree. The delivery fee decreases as the number of trees purchased increases. The table below represents the total cost of x trees purchased, including delivery fees.
Which best describes why the function is nonlinear?
The rate of change between 1 and 2 trees is different than the rate of change between 2 and 3 trees.
The rate of change between 1 and 2 trees is different than the rate of change between 1 and 3 trees.
The rate of change between 2 and 3 trees is different than the rate of change between 3 and 4 trees.
The rate of change between 2 and 3 trees is different than the rate of change between 3 and 5 trees.
Answer:
C
Step-by-step explanation:
I think
Answer:
Step-by-step explanation:
d) The rate of change between 2 and 3 trees is different than the rate of change between 3 and 5 trees.
Number of tree purchased Total Cost ($)
1 60
2 120
3 180
4 240
5 290
For the linear function rate of change is constant.
Now, between 2 and 3 trees rate of change is given by
Now, between 3 and 5 trees rate of change is given by
This is clearly that the rate of change isn't constant. Therefore, the function is non-linear.
so,
d) The rate of change between 2 and 3 trees is different than the rate of change between 3 and 5 trees.

Find all numbers whose absolute value is 5.
If there is more than one, separate them with commas.
If there are no such numbers, click on "None".
Answer:
5 , |-5|
Step-by-step explanation:
2 of the above are the absolute value of 5
The two numbers whose absolute value is 5 are 5 and -5.
Numbers whose absolute value is 5 can be both positive and negative.
The absolute value of a number is its distance from zero on the number line, so any number that is 5 units away from zero in either the positive or negative direction will have an absolute value of 5.
Here are the numbers whose absolute value is 5:
5 (positive 5, because it's 5 units to the right of zero)
-5 (negative 5, because it's 5 units to the left of zero)
Hence, 5 and -5 are the two numbers whose absolute value is 5.
