Solve for the value of m.
(4m-5)
(3m+3)
Answer:
put the value m=1/2
3m(4m+5)=3
⇒3×1/2(4×1/2+5)+3
⇒3/2(2+5)+3
⇒6/2+15/2+3
⇒37 ans.
Step-by-step explanation:
For the equation, (4m-5)(3m+3)=37 value of m are 2.21 and -1.96
Equation consist of 2 expression equivalent to each other.
Given the following equation:
(4m-5)(3m+3)=37
To calculate the value of m as follows:
4m(3m+3)-5(3m+3)=37
12m²+12m-15m-15=37
12m²-3m-52=0.................................m)
Using discriminant formula:
[tex]d=b^2-4ac.............................1\\x=\dfrac{-b\pm\sqrt d}{2a}............................2[/tex]
Here, from equation m)
a=12, b=-3, c=-52
Substituting in equation 1
d=(-3)²-4(12)(-52)
d=2505
√d=50.04
[tex]m=\dfrac{3\pm 50.04}{2\times 12}\\\\m=2.21 \text{\ and\ } m=-1.96[/tex]
Thus value of m are 2.21 and -1.96

what is the perimeter write your solution
Answer: 88in
Step-by-step explanation:
As he has doubled the sides, the length would now be 24 and the width would be 20.
So then, to work out the perimeter you have to add up all of the sides.
24+24+20+20=88in

Step-by-step explanation:
A bag contains eight batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select two batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected without replacement.
Answer:
7*6*5*4*3 = 7P5 = 2520
Step-by-step explanation:
There will be 56 points in the sample space when two batteries are selected without replacement from the bag.
To determine the number of points in the sample space when selecting two batteries without replacement, we can use the counting principle.
The counting principle states that if there are m ways to do one task and n ways to do another task, then there are m * n ways to do both tasks together.
In this case, the first battery can be selected in 8 ways (since there are 8 batteries in the bag).
After selecting the first battery, there are 7 remaining batteries in the bag. For the second battery, there are 7 ways to select it (one less than the previous selection).
Therefore, the number of points in the sample space is given by multiplying the number of possibilities for the first selection (8) by the number of possibilities for the second selection (7):
8 * 7 = 56
There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

Error Analysis! Answer both parts of the question.
Kaitlyn solved the equation 5y = 15 and found the answer to be y = 75.
(Problem down below in file)
Part A: In a complete sentence or two, explain what Kaitlyn's error was. What did she do wrong?
Part B: What is the correct answer? Show your work and/or explain your reasoning.
Answer:
Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side
so you would do 5/5 - cancels out
15/5=3
y=3
Step-by-step explanation:
have a great day :D
Answer:
y = 3Explanation (Part A):
She was supposed to divide five both sides. However, she divided one side by five and multiplied five on the other side, which makes her answer incorrect. She got confused that if any side is divided by a number, the other side must be divided by that same number.Solution (Part B):
5y = 15=> 5y/5 = 15/5=> y = 3The correct answer must be 'y = 3'.

The Boston Red Sox had 949 runs in their 2004 season. In their 2015 season, they had 748 runs. Find the rate of change in runs.
Answer: -18.27 per year
Step-by-step explanation:
The difference in years is:
= 2015 - 2004
= 11 years
In those 11 years, the runs decreased from 949 to 748.
The total decrease is:
= 949 - 748
= 201 runs
The rate of change is:
= 201 / 11
= 18.27 per year
Since it is reducing, the rate is:
= -18.27 per year

-2/3 -2/3
5/3=q
q=5/3
Answer: q = 5/3
Step-by-step explanation: Step 1: Flip the equation.
q + 2/3 = 7/3

A bowl contains equal-sized gumdrops. If the bowl has 30 green gumdrops and 1 blue gumdrop, plot an X on the number line below which could represent the probability of randomly choosing a green gumdrop from the bowl.
Explain how you determined your answer.
Answer:
≈ 0.97
Step-by-step explanation:
Given that :
Number of green gum drops = 30
Number of Blue gum drops = 1
Total number of gum drops :
(Number of blue + number of green gum drops)
(30 + 1) = 31
Probability = Required outcome / Total possible outcomes
P(green gum drops) = number of green drops / total number of gum drops
P(green gum drops) = 30 / 31 = 0.967 ≈ 0.97

1. A ball is kicked up from a platform 36 feet above the ground. The height of
the ball h(t) above the ground (measured in feet) can be modeled by the
function h (t)
-3t2 + 12t + 36, where t represents the amount of time
(in seconds) since the ball was kicked. How long to the nearest second did it
take the ball to hit the ground?
-
seconds to hit the ground
Answer:6
Step-by-step explanation:
So when the ball hits the ground -3t^2+12t+36 must equal 0
So you can factor a -3 out
-3(t^2-4t-12)=0
Factor -3(t-6)(t+2)=0
T-6=0 t+2=0
T=6 t=Negative 2
And since time can’t be negative the answer is 6
