Hi there!

First, the area cannot be 15×8, or 120 cm^2, because this isn't a normal rectangle.

We can get our answer to what the length of the odd-looking lines are by seeing that the length of the top line of the cutout is equal to half of the 8 cm^2 line. Half of eight is four, so each line in the square cutout is a length of four.

So, our diameter is 15+8+8+4+4+4+4+4, or 52 cm^2.

Here is where even I'm getting stumped!

I think the answer is 100, because if you subtract 15×8=120 and subtract 4 (the length of the small sides) × 5 (the amount of them) you get 100 cm^2.

Try it, and see if it works!

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer. I want to be able to assist more users one-on-one, as well as to move up in rank! :)

Karl had planned to drive for 1023 hours on a certain day during his road trip. When he became sleepy, however, he decided to de

netineya [11]

Since Karl became sleepy and decided to decrease his driving time by 25%, he drove <u>767.25 hours</u> that day.

<h3>What is driving time?</h3>

Planned driving time is the estimated time that Karl planned to drive between two points or to one's destination.

The Actual driving time is the actual time that it took Karl to drive from one point to his destination.

Driving time can be estimated or calculated by dividing the distance by the speed.

<h3>Data and Calculations:</h3>

The planned driving hours on a certain day = 1,023 hours

Decrease in driving time = 25%

Percentage of hours Karl drove = 75% (100 - 25)

Hours drove that day = 767.25 hours (1,023 x 75%)

Thus, Karl drove <u>767.25 hours</u> that day.

If ab = 8 and a^2+b^2=16, then what is the value of (a+b)^2?

aksik [14]

$ab = 8$ & $a^{2} + b^{2} = 16$ so , $( a+b )^{2} = 32$ .

<u>Step-by-step explanation:</u>

Here we have , ab= 8 & a^2+b^2=16 i.e. $ab = 8$ and $a^{2} + b^{2} = 16$ .

We need to find value of (a+b)^2 i.e. $(a+b)^{2}$ :

It's and identity and we know that $( a+b )^{2} = a^{2} +b^{2} +2ab$

⇒ $( a+b )^{2} = a^{2} +b^{2} +2ab$

⇒ $( a+b )^{2} = (a^{2} +b^{2}) +2(ab)$

⇒ $( a+b )^{2} = (16) +2(8)$

⇒ $( a+b )^{2} = (16) +(16)$

⇒ $( a+b )^{2} = 32$

∴ $ab = 8$ & $a^{2} + b^{2} = 16$ so , $( a+b )^{2} = 32$ .

Pls help im failing i need help ASAP

The answer is choice 1 because when you divide 2 numbers with the same base and different exponents you subtract the second exponent from the first.

p^-m / p^-n = p^(-m - (-n))

CHOICE 1
