Width of the rectangle is 16 cm
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then length = 4x. Find width.
Area of the rectangle = length × width
⇒ 1024 = x × 4x
⇒ 4x² = 1024
⇒ x² = 1024/4 = 256
⇒ x = √256 = 16
Answer:
2(2x + 1)(3x + 1)
Step-by-step explanation:
given
12x² + 10x + 2 ← factor out 2 from each term
= 2(6x² + 5x + 1) ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term
product = 6 × 1 = 6, sum = + 5
The factors are + 3 and + 2
Use these factors to split the middle term
6x² + 3x + 2x + 1 ( factor the first/second and third/fourth terms )
= 3x(2x + 1) + 1(2x + 1) ← take out the common factor (2x + 1)
= (2x + 1)(3x + 1)
12x² + 10x + 2 = 2(2x + 1)(3x + 1) ← in factored form
Do 65/100. Gives you 0.65 right.
So then do 0.65*40 = 26
Answer is 26 minutes.
