For each parallelogram find the length of the base or height the first parallelogram has the area of 60 meters square the base i

Lynna [10]

Answer:

5 m

Step-by-step explanation:

You know the area of a parallelogram is the product of its base length and height:

area = base × height

Fill in the given values, and solve for height:

60 m² = (12 m) × height

(60 m²)/(12 m) = height = (60/12) m

height = 5 m

The height is 5 meters.

Delaware was the first state to enter the Union and Hawaii was the 50th. If we order the positions of entry for the rest of the

Anna71 [15]

Answer:

State A was the <u>12th</u> state to enter the Union. State B was the <u>11th</u> state to enter the Union.

Step-by-step explanation:

Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:

x*(x+1) = 132

x² + x - 132 = 0

Using quadratic formula:

$x = \frac{-b \pm \sqrt{b^2 -4(a)(c)}}{2(a)}$

$x = \frac{-1 \pm \sqrt{1^2 -4(1)(-132)}}{2(1)}$

$x = \frac{-1 \pm 23}{2}$

$x_1 = \frac{-1 + 23}{2}$

$x_1 = 11$

$x_2 = \frac{-1 - 23}{2}$

$x_2 = -12$

The negative solution has no sense in the context of our problem, then the solution is x = 11.
