We can use the formula for area of a triangle to solve this problem A = (1/2)ab where a is the altitude or height and b is the base also we know that a = 4b in this problem and we know that A = 18 sq ft so 18 = (1/2)(4b)b 18 = 2b2 9 = b2 b = 3 so the base is 3 and the height is 4 times that a = 4(3) = 12 (height of the sail Hope this helps
The y-intercept point is (0,3)
The common denominator is 12
Answer
-44
Step-by-step explanation:
9(a+2b)+c
9(-3+2*-2)+1
9(-3-2)+1
9(-5)+1
-45+1
-44
