If x = 8 units, y = 3 units, and h = 1 unit, then what is the area of the parallelogram shown above?

Answers

Answer:

8unit²

Step-by-step explanation:

The Area of a parallelogram :

Length of base * height

Length of base, x = 8 units

Height, h = 1 unit

Area = Length of base * height

Area = 8 units * 1 unit

Area = 8unit²

What is the value of x?

Answers

Answer:

Step-by-step explanation:

Since UV is a tangent then ∠ WUV = 90°

WZ = WU = x - 1 ( both radii of the circle ) , then

WV = x - 1 + 2 = x + 1

Using Pythagoras' identity in the right triangle

WU² + UV² = WV² , that is

(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL

x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1

5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides

4x² - 20x + 16 = 0 ← divide through by 4

x² - 5x + 4 = 0

(x - 1)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 4 = 0 ⇒ x = 4

But x ≠ 1 as radius x - 1 = 0

Thus x = 4 → B

Answer:

Step-by-step explanation:

7m+19/2=13

7m +19 = 13 x 2

7m = 26 - 19

7m+19/2=13

7m = 26/2 - 19/2

7m = 7

m = 7/7 = 1

Both ways r correct !!
