Answer:
35
Explanation:
Recall that (a+b)^2=a^2+2ab+b^2.
We can rearrange it in a way that would make it easier to solve our problem:
(a^2+b^2)+2ab
Now, we just plug in 25 for a^2+b^2, and plug in 5 for ab:
25+2*5
=25+10
=35

Juan is rappelling down a 495-foot cliff at a rate of 6 feet per second. Which equation would represent the height Juan is above
ss7ja [257]

Answer:

The equation is H = 495 -6t

Step-by-step explanation:

Here, we want to write an equation that will represent the height Juan is above the ground, after t seconds.

The height we want to calculate is H. The initial height is 495 foot;

At the first second, the decrease in height will be 6 * 1, at the second 6 * 2 and thus at t seconds, the decrease in height will be 6 * t = 6t

Ask the height after t seconds will be;

H = 495 - 6t

Where t represents the time in seconds
