First question: 2x = 50
Explanation:
“2 times as many” in this situation means that the pages justin read (50) is twice as Colin’s. Meaning that to find the number of pages Colin’s read, we will have to divide 50 by 2.
2x = 50 is an equivalent representation of that.

2nd question:
(Choose these correct statements):
• 9h represents how much money Sofia earns babysitting for h hours.
• Sofia babysat for 3 hours.
• If Sofia babysits for 5 hours, she will earn $45

Answer:

B) $9d^8$

Step-by-step explanation:

To find the expression equivalent to $(3d^4)^2$ , we must simplify the given expression. This can be done by applying an exponent rule:

$(a*b)^x=a^xb^x$

In the context of our problem, we would have:

$(3*d^4)^2$

Therefore, when that exponent is distributed, we get:

$(3^2d^8)$

Simplified, we have:

$9d^8$

Each side of a square is increasing at a rate of 4 cm/s. at what rate is the area of the square increasing when the area of the

7nadin3 [17]

The question is related to application of derivatives .

Let A represents the area and s represent the side length .

$A = s^2$

$25=s^2$

$s =\sqrt{25} = 5$

$A = s^2$

Differentiating both sides with respect to t

It is given that ds/dt = 4cm/s

Substituting the values of s, ds/dt and on multiplying them, we will get

dA/dt = 2(5)(4) = 40 cm^2/s

Therefore rate of change of area when area= $25 cm^2$ and rate of change of side is 4 cm/s is 40 $cm^2/s .$
