Answer:
add all of the sides together
Step-by-step explanation:
84 is a composite number. 84 = 1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, or 7 x 12.
Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.
Answer:
22.8
Step-by-step explanation:
the rectangular has :
the length CD =√[(3+3)²+(0-5)²]
= √(36+25) = √61 = 7.8
the width BC =√[(5-3)²+(3-0)²]
=√(4+9 =√13 = 3.6
so, the perimeter = 2(7.8 + 3.6)
= 2× 11.4 = 22.8
In order to calculate the Circumference, You can Use the formula:
C = 2πr
C = πd
They are valid one's, depends, on the given value, either diameter or radius

Answer:

Step-by-step explanation:
Given function is,
f(x) = -8x² + 4
Step to find the inverse of the function,
Step 1
Write the function in the form of an equation,
y = -8x² + 4
Step 2
Interchange the variables 'x' and 'y',
x = -8y² + 4
Step 3
Solve the equation for y,
x = -8y² + 4
x - 4 = -8y²
-x + 4 = 8y²
y² = 

Therefore, inverse of the function f(x) will be,
