Answer:
Step-by-step explanation:
f(x) = x²+3
f(a+1) = (a+1)²+3 = a²+2a+4
Step-by-step explanation:
Length of base = 20cm
We will take the base as "b"
Area of a triangle = 1/2 x base x height
So the total area = 360 square feet
360 square feet = 1/2 x b x 36
360 = 36b /2
360 = 18b
b = 360/18
b = 20
So, Length of base = 20 cm
Let's check:
1/2 x 20 x 36 = 360
Which is the correct area!
Hope this helps!

Answer:
Step-by-step explanation:
7x - 15 = 4x - 12
3x - 15 = -12
3x = 3
x = 1
y = 7(1) - 15
y = 7 - 15
y = -8
(1, -8)
It is 238 that is not the answer so yea
