Answer 2

Answer:

Final answer:

In this Mathematics problem, you're searching for two numbers that, when multiplied, equal 3969 and, when added, equal 126. By factoring 3969, we find that the numbers 63 and 63 meet both criteria.

Explanation:

This Mathematics problem falls under factoring in Algebra. You are trying to find two numbers that multiply to 3969 (the product) and add up to 126 (the sum). The numbers you're looking for are 63 and 63. Let's see why.

First, factor 3969. The factors of 3969 are 1, 3, 9, 27, 81, 147, 441, 1323, and 3969. Looking at these factors, we see that only 63 and 63 multiply together to give 3969.

Now, check if they also add up to 126. Indeed, 63 + 63 equals 126, confirming that these are the two numbers you're looking for.

I’m having a hard time understanding substitution. Please help!

Answers

$b_1=(2A)/(h)-b_2$

Step-by-step explanation:

Given expression is;

$A=(h(b_1+b_2))/(2)$

Solving for $b_1$

Multiplying both sides by 2

$2*A=(h(b_1+b_2))/(2)*2\n2A=h(b_1+b_2)$

Dividing both sides by h

$(2A)/(h)=(h(b_1+b_2))/(h)\n(2A)/(h)=b_1+b_2$

Subtracting $b_2$ from both sides

$(2A)/(h)-b_2=b_1+b_2-b_2\n(2A)/(h)-b_2=b_1\nb_1=(2A)/(h)-b_2$

$b_1=(2A)/(h)-b_2$

Find the sum of the following nine products: 1 × (10 – 1), 2 × (10 – 2), 3 × (10 – 3), … , 9 × (10 – 9)

Answers

Answer:

165

Step-by-step explanation:

We solve the first 5

1*(10-1)=9

2*(10-2)=16

3*(10-3)=21

4*(10-4)=24

5*(10-5)= 25

and notice

when you go from 6 on its getting the same number because say 3*(10-3) = 3*7 and 7*(10-7) = 7*3 and 7*3 = 3*7 so

You add the first 5 integer you solved up

9 16 21 24 25 = 95

and then you double it no extra 25

and then you get 165 = answer

Answer:

9, 16, 21, 9
