Examine parallelogram ABCD.

Mathematics
1 answer:
mario62 [17]3 years ago
3 0

Answer:

Step-by-step explanation:

In a parallelogram, the opposite sides are parallel and also equal. The opposite angles are also equal.

In parallelogram ABCD, side AD is parallel to side BC. Also, side AB is opposite and parallel to side CD. This means that AB = CD

Sides CD and AB have lengths of y + 18 and 4y, respectively. Therefore,

y + 18 = 4y

Subtracting y from the left hand side and the right hand side of the equation, it becomes

y + 18 - y = 4y - y

3y = 18

y = 18/3 = 6

Therefore, the length of AB is

AB = 4y = 4 × 6

AB = 24

What is the equation of a line, in general form, that passes though points (-1,2) and (5,2)?
Tom [10]

Answer:

A

Step-by-step explanation:

To write the equation of the line. first calculate the slope using the slope formula.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{2-2}{5--1}= \frac{0}{6} = 0

Since the slope of this line is 0, it is horizontal and has the form y=b where b is the y-coordinate. So y = 2 is the equation. In general form, it would be y-2 = 0

Please help. A rectangle's length and width are in a ratio of 7:3. The area is 84 square feet. What are the
GalinKa [24]

Answer:

length = 14 feet

width = 6 feet

Step-by-step explanation:

A = 84 feet square

ratio of length and width = 7 : 3

total ratio of length and width 10 = a

length = (7/10)a

width = (3/10)a

A = length x width = (7/10)a x (3/10)a = (21/100)a² = 84

a² = 84 x 100 : 21 = 400

a = 20 feet

length = 7/10 x 20 = 14 feet

width = 3/10 x 20 = 6 feet
