Answer:
it will be 147
Step-by-step explanation:
12x12=144
Use Pythagoras theorem:
a^2 = b^2 + c^2
-15^2 + 18^2 = a^2
a^2 = 99
a = root of 99

Answer:
$2650
Step-by-step explanation:
If Jack's earnings are represented by e, then we have ...
10% × e = $256
Multiplying by 10 gives ...
100% × e = $2560
Jack earned $2650 in the summer.
_____
100% = 1
3*16-2*4=48-8=40 Try this, its my only guess :(
Hello!
To solve this, lets put it into a system of equations where w=width and L=length.
2w+2L=80
L-8=w
To solve, we see that w=L-8. We can substitute this in the first equation to find L and then w.
2(L-8)+2L=80
2L-16+2L=80
4L-16+80
4L-16=80
4L=96
L=24
Now that we know L=24, we can find w. 24-8=16. Now we know that L=24 and w=16.
Lets check our answer. In our original system of equations, we have 48+32=80, which is true, and 24-8=16. Also, the perimeter must equal 80. 16+16+24+24=80.
As our final answer, the width of the pool is 16 feet, and the length is 24 feet.
Hope this helps!
