Write that as 7x. Writing it as x7 could lead to confusion. 7*x would be OK.
Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
Answer:
Prime numbers are whole numbers that are greater than 1 which only have factors of 1 and itself.
The area of the triangle is 1358 square feet
Step-by-step explanation:
Area = 1/2 (base * height)
Area = 1/2 (56 * 48.5)
Area = 1/2 (2716)
Area = 1358
