Answer:

\large\boxed{(8a^2-6ab+4b^2)-(3a^2+5ab-4b^2)=5a^2-11ab+8b^2}

Step-by-step explanation:

(8a^2-6ab+4b^2)-(3a^2+5ab-4b^2)\\\\=8a^2-6ab+4b^2-3a^2-5ab-(-4b^2)\\\\=8a^2-6ab+4b^2-3a^2-5ab+4b^2\qquad\text{combine like terms}\\\\=(8a^2-3a^2)+(-6ab-5ab)+(4b^2+4b^2)\\\\=5a^2-11ab+8b^2

The area of a square is increasing at a rate of 24 centimeters squared per second. Find the rate of change of the side of the sq
velikii [3]

Answer:

3cm/s

Step-by-step explanation:

Area of a square is expressed as:

A = L²

Rate of change of area is expressed as:

dA/dt = dA/dL•dL/dt

Given that

dA/dt = 24cm²/s

L = 4cm

Required

dL/dt

Since dA/dl = 2L

dA/dl = 2(4)

dA/dl = 8cm

Subatitute the given values into the formula

24 = 8 dL/dt

dL/dt = 24/8

dL/dt = 3cm/s

I NEED HELP ON THIS CONSTRUCTED RESPONSE QUESTION! :(
zavuch27 [327]

Answer:


Step-by-step explanation:

She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.

$33.50 - $13.50 = $20

Admission is $20.

(a) Let y represent total cost. Let x represent the number of ride tickets.

(b) y = 0.75x + 20

(c) The total cost is the cost of x ride tickets plus the admission.

x ride tickets cost 0.75x.

Admission is a fixed 20.

Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.

For an annual membership fee of $500,Mr.Bailey can join a country club that would allow him to play a round of golf for $35. Wit
IRISSAK [1]

Answer:

25 rounds

Step-by-step explanation:

Let

x -----> the number of rounds of golf

y ---> total charges to play

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

<em>Membership</em>

y=35x+500 ----> equation A

The slope is  m=$35 per round

The y-intercept b=$500 (annual membership fee)

<em>Non-Membership</em>

y=55x ----> equation B

The slope is  m=$55 per round

The y-intercept b=$0

Equate equation A and equation B

55x=35x+500

solve for x

55x-35x=500

20x=500

x=25\ rounds

For x=25 rounds the cost to be the same with and without a membership
