What is the area of a trapezoid ABCD with bases AB and CD

Elan Coil [88]3 years ago

If you draw a perpendicular to CD from point A or point B, you will create a right triangle with one leg 5 and hypotenuse (BC or DA) 13. The other leg of this triangle is the height of the trapezoid:

... h = √(13² -5²) = 12

The area is this height multiplied by the average base length:

... Area = (12 cm)×(10 cm +20 cm )/2 = 180 cm²

A= a+b/2h =10+20/2 x13 =195

I believe 195 is correct if not, I’m so sorry

aleksandrvk [35]
This is a working backwards problem.  You know he has $35 at the end.  Before he gave his brother $5, he would have $40, which is half of what he had before he bought the clothes, so he would have had $80.  Before he spent the $40 on shoes, he would have had $120, so the answer is $120.

Find the equation of the line shown.
Luda [366]

Answer:

y = -x + 9

Step-by-step explanation:

✔️Find the slope using (9, 0) and (7, 2):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1

Slope (m) = -1

✔️Find the y-intercept (b):

The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9

✔️Substitute m = -1 and b = 9 into y = mx + b

Thus,

y = -1(x) + 9

y = -x + 9

Write the equations of three distinct lines that have the same y-intercept,-1.
guajiro [1.7K]
Three possible answers are:
y = 2x-1
y = 5x-1
y = -3x-1

All of them have the same y intercept of -1. The slopes are the only thing that differ.

Any linear equation can be written in the form y = mx+b where
m = slope
b = y intercept
