Step-by-step explanation:
1. a²=25²-15²
a²=(25-15)(25+15)
a²=10×40
a=20
2.b²=10²-6²
b²=(10-6) ×(10+6)
b²=4×16
b=8
Remember:

When you square root something, you have to find two same numbers that when multiplied will give you that original number.
Hope that helped :)
Step-by-step explanation:
the slope of a line is the ratio y/x.
that means, when going from one point to the other, how many units y changes, when x changes a certain number of units.
the sign indicates the direction of the change (+ for larger and - for smaller).
so, here x changes by 6 units (from -3 to 3), and y changes by -2 units (from 4 to 2).
therefore, the slope is
-2/6 = -1/3
She would have $800 left.
$4000 - $2800= 1200
1200 is how much she spent the last 3 months
1200/ 3= 400
400 * 5= $2000
2800- 2000= $800
