Caillan's pocket money increased 20-15=5 dollars per week, or to 20-15=1.33 of it's original amount. This is a 33% increase.
No two <em>intergers</em> can solve this problem. If you're not in Algebra II yet, the answer is probably "none."
Just look at the factor pairs of 25:
1 × 25
-1 × 25
5 × 5
-5 × -5
Clearly none of those can add up to 6.
If you want the more complex answer, I'll show you how here. If you don't understand why it doesn't work, that's okay. I just want you to see that there's not an actual answer to the problem.
a+b = 6
a = 6-b
ab = 25
(6-b)b = 25
6b -b² = 25
-b² + 6b = 25
b² -6b = -25
Factor by splitting the middle.
Half of -6 is -3, (-3)² = 9. Add this to each side.
b² -6b + 9 = -16
Factor the perfect square trinomial.
(b-3)² = -16
Take the square root of each side.
b-3 = 4i
b = 3+4i
a+b = 6
a+3+4i = 6
a= 3-4i
<em>(The "i" stands for an imaginary number, specifically, the square root of -1.)</em>
The answer is c. 48 because angle 3 and 132 equals 180 because they are supplementary angles. So... 180 - 132 = 48 <—- angle 3

Answer:
50 ft
Step-by-step explanation:
The sum of length and width is half the perimeter, so ...
L + W = P/2
L = P/2 - W = (180 ft)/2 - 40 ft = 50 ft
The length of the garden is 50 ft.
