Answer:
36 square feet
Step-by-step explanation:
To get the answer you need to find the area of the triangle and subtract area of the rectangle.
7*12/2 = 42
42 - 3*2 = 36
Y = (x+3)^2 - 5 here's the answer hope it helps
Its way too small i cant see the question.
Answer:
x = 7
y = 2
Step-by-step explanation:
x² - y² = 45
(x+y) (x-y) = 45
x + y = 9 (known)
9 x (x-y) = 45
x - y = 5
y = x-5
x + (x - 5) = 9 (substitute)
2x = 14
x = 7
y = 2
