it is -4
Step-by-step explanation:
if you do it From left to right it's -4
<u>Define x:</u>
Let the width be x.
width = x
Length = 4x
<u>Given the area, find Length and Width:</u>
The area is 100 cm²
Area = Length x Width
x(4x) = 100
Evaluate the Left Hand Side:
4x² = 100
Divide by 4:
x² = 25
Square root both sides:
x = 5
<u>Find the Width and the Length:</u>
Width = x = 5
Length = 4x = 4(5) = 20
<u>Find Perimeter:</u>
Perimeter = 2( 5 + 20) = 50 m
Answer: Perimeter = 50 m
The problem is meant to be set up like this:
100÷ 5 × 4 + 4^3
simply because it is 4 cubed at the end.
and the answer is 144! :)))))
Step-by-step explanation:
π= 3.14
Given
Circumference = 12.56 units
First calculating radius
so 2πr = 12.56
2 * 3.14 * r = 12.56
6.28 r = 12.56
Therefore r = 2 units
Now calculating Area
Area = πr²
= 3.14 * 2²
= 12.56 square units
What is the modulus of 2 – 3i?
