Answer 1
Answer:

Answer:

Step-by-step explanation:

The given equation is:

x^(2)-8x-20

Simplifying the above equation, we get

x^(2)-10x+2x-20

x(x-10)+2(x-10)

(x+2)(x-10)

therefore, the equation x^(2)-8x-20 matches with (B) (x+2)(x-10).

The given equation is :

x^(2)+8x-20

Simplifying the above equation, we get

x^(2)+10x-2x-20

x(x+10)-2(x+10)

(x-2)(x+10)

therefore, the equation x^(2)+8x-20 matches with (D) (x-2)(x+10)

The given equation is:

x^(2)-x-20

Simplifying the above equation, we get

x^(2)-5x+4x-20

x(x-5)+4(x-5)

(x+4)(x-5)

therefore, the equation x^(2)-x-20 matches with (A) (x+4)(x-5).

The given equation is:

x^(2)-9x-20

This equation ca't be firther simplified or factorised, thus the equationx^(2)-9x-20 matches with (C) Prime.

Answer 2
Answer:

the correct matches for the polynomials are:

A) (x – 5)(x + 4) matches with x^2 – x – 20.

B) (x – 10)(x + 2) matches with x^2 + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x^2 – 9x – 20.

How did we arrive at these assertions?

Let's factor each trinomial and match them with their factored forms:

x² – 8x – 20:

To factor this trinomial, we need to find two numbers that multiply to give -20 and add up to -8. The numbers that satisfy these conditions are -10 and 2. Therefore, the factored form is (x – 10)(x + 2). Match: A.

x² + 8x – 20:

For this trinomial, we once again look for two numbers that multiply to give -20 and add up to 8. The numbers are -2 and 10. Hence, the factored form is (x – 2)(x + 10). Match: D.

x² – x – 20:

Here, we seek two numbers that multiply to give -20 and add up to -1. The numbers -5 and 4 satisfy these conditions. Thus, the factored form is (x – 5)(x + 4). Match: A.

x² – 9x – 20:

Similar to the previous trinomials, we search for two numbers that multiply to give -20 and add up to -9. The numbers are -10 and 1. So, the factored form is (x – 10)(x + 1). Match: B.

Matching the terms with their factored forms:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.

Therefore, the correct matches are:

A) (x – 5)(x + 4) matches with x² – x – 20.

B) (x – 10)(x + 2) matches with x² + 8x – 20.

C) Prime does not match any of the given terms.

D) (x – 2)(x + 10) matches with x² – 9x – 20.

Which of the numbers below are exactly divisible by 9 115 504 968 646 882

Answers

504 and 882 are both exactly divisible by 9, which means that the quotient will come out as a whole number with no decimals when the number is divided by, in this case, 9. 

Final answer:

Applying the rule that a number is divisible by 9 if the sum of its digits is divisible by 9, we find that 504 and 882 from the list (115, 504, 968, 646, 882) are divisible by 9.

Explanation:

To identify numbers that are divisible by 9, we can follow this rule: A number is divisible by 9 if the sum of its digits is divisible by 9. So, applying this rule to the numbers given (115, 504, 968, 646, 882), we find:

115: 1+1+5 = 7, which is not divisible by 9.

504: 5+0+4 = 9, which is divisible by 9. So 504 is divisible by 9.

968: 9+6+8 = 23, which is not divisible by 9.

646: 6+4+6 = 16, which is not divisible by 9.

882: 8+8+2 = 18, which is divisible by 9. So 882 is divisible by 9.

How many quarts does it take to fill a kitchen sink

Answers

The average kitchen sink has a width of approximately 23.5 inches, a length of approximately 31.5 inches, and a depth of approximately 21 inches. 

Multiplying these values together, we can see that the volume of the average kitchen sink is about 15545.25 cubic inches.

The conversion of cubic inches to liquid gallons is 1 cubic inch = approximately 0.004329 gallons.

Multiplying these numbers, we can see that 15545.25 cubic inches is the same as approximately 67.29538725 gallons. Now, we just have to multiply that number by 4, since there are 4 quarts in a gallon.

67.29538725 * 4 = 269.181549

It takes approximately 269.181549 quarts to fill the average kitchen sink.

Step-by-step explanation:

Three times a number s plus 4 times a number y is 1 more than 6 times the number s. solve for s

Answers

Three times a number s => 3s
4 times a number y => 4y
1 more than 6 times the number s => 6s + 1

The full equation would be:

3s + 4y = 6s + 1

Solve for s.
group same letter numbers and change its signs.
3s - 6s = -4y + 1
-3s = -4y + 1
solve for s. divide both sides by -3
-3s / -3 = (-4y + 1) / -3
s = (4y - 1) / 3 
"Three times a number S" is 3s.
"Plus 4 times a number y" is + 4y
"is" =
"1 more than" is 1 +
"6 times the number S" is 6s.
The equation is:
3s+4y=1+6s
subtract 3s:
4y = 1 +3s
subtract 1:
4y - 1 = 3s
Divide everything by 3:
4y/3 - 1/3 = s
