a. The equation will be of the form x(x+2) = 80.

b. The two numbers are 8 and 10.

What is an integer ?

An integer is a number which has no decimal value.

According to the given question we have to write an equation representing the fact the product of two consecutive even integers is 80.

Let us represent the smaller integer x and the greater integer by (x+2).

As even numbers comes after every 2 digits.

∴ x(x+2) = 80

x² + 2x = 80

x² + 2x - 80 = 0

x² + 10x - 8x - 80 = 0

x(x+10) - 8(x+10) = 0

(x+10) = 0 OR (x-8) = 0

x = -10 OR x = 8.   ( x = 8 is the valid option as it satisfies the given equation)

The two integers are 8 and 10.

subtract the sum of 12ab-10b²-18a² and 9ab+12b²+14a² from ab+2b² and 3b²-a²​

Answers

Answer:

3a² + 3b² - 20ab

Step-by-step explanation:

Sum of 12ab-10b²-18a² and 9ab+12b²+14a²

12ab - 10b² - 18a² + 9ab + 12b² + 14a²

= 14a² - 18a² + 12b² - 10b² + 12ab + 9ab

= -4a² + 2b² + 21ab

Sum of ab + 2b² and 3b²- a²

= ab + 2b² + 3b²- a²

= -a² + 2b² + 3b² + ab

= -a² + 5b² + ab

Subtract

-a² + 5b² + ab - (-4a² + 2b² + 21ab

= -a² + 5b² + ab + 4a² - 2b² - 21ab

pound. If you had $10 to spend, would you be able to buy a greater weight of
peaches or of grapes? Explain your answer.

Answers

Answer: A greater weight of peaches will be bought

Step-by-step explanation:

The unit rate for peaches = $2.00 per pound.

The unit rate for grapes = $2.50 per

pound.

Amount to spend = $10

Weight of peaches to buy with $10 = $10 / $2.00

= 5 pounds

Weight of grapes to buy with $10 = $10 / $2.50

= 4 pounds

Therefore, a greater weight of peaches will be bought as 5 pounds will be bought instead of 4 pounds for grape.

PLEASEE HELP

Answers

Ok so the answer is 88 feet^2.

Explanation: First we would find the area of the pool. 6 times 12 is 72.
Since 4 feet is added add that to 6 AND 12.
Now multiply 10 and 16. 10 * 16 = 160.
Subtract 72 from 160. 160-72= 88 ft^2

Suppose y varies directly with x, and y=98 when x=14. Write the direct
variation equation that relates x and y.

Answers

Answer:   y = 7x

===========================================================

Explanation:

Since y varies directly with x, this means y = kx for some constant k.

Plug in y = 98 and x = 14 to solve for k

y = kx

98 = k*14

98/14 = k

7 = k

k = 7

Therefore, y = kx updates to y = 7x which is the equation we're after.

Answer:

y = 7x

Step-by-step explanation:

The general formula for direct variation is y = kx, where k is the constant of proportionality.  If y = 98 when x = 14, then k must be 98/14. or 7, and so

y = 7x is the desired direct variation equation.
