Answer:
2(x^2-12x-7)
Step-by-step explanation:
Answer:
49.132 m²
Step-by-step explanation:
Area of a triangle=1/2(base×height)
Area=1/2(6×8)
Area=24 m²
Now
Area of semi circle=πr²/2
Area=(3.14)(8÷2)²/2
Area=(3.14)(4)²/2
Area=(3.14)(16)/2
Area=50.265/2
Area=25.132 m²
Now
Total area=area of triangle+semi-circle
Total area=24+25.132
Total area=49.132 m²
Robert is incorrect: Surface are of A is 30 + 30 + 42 + 42 + 35 + 35 = 214 square centimeters. Surface area of B is 120 + 120 + 168 + 168 + 140 + 140 = 856 square centimeters. B's surface area is 4 times as great as A's.
Answer:
gradient = 9
Step-by-step explanation:
Note that is a measure of the gradient.
Differentiate y using the power rule
(a) = na
Given
y = x² + 5x - 3, then
= 2x + 5
x = 2 : = 2(2) + 5 = 4 + 5 = 9 ← gradient
