Answer:

130 cm^2

Step-by-step explanation:

To calculate area of a trapezoid we divide the sum of bases by two then multiply it with height

(17 + 9) ÷ 2 × 10 = 130 cm^2

Answer:

The answer is option b 130cm²

Area of a trapezium is 1/2(a + b) × h

where 'a' and 'b' are the parallel sides of the trapezium

h is the height

From the picture above

h is 10cm

'a' and 'b' are 17cm and 9 cm respectively

Area of the trapezium = 1/2 ( 17+9)× 10

= 1/2× 26 × 10

= 13 × 10

= 130cm²

Hope this helps

Answer:

Option A

Step-by-step explanation:

Given expression:

  • 3x² - 10x - 8

<u>Option A</u>

⇒ (x - 4)(3x + 2)

⇒ (x × 3x) + (2 × x) + (-4 × 3x) + (-4 × 2)

⇒ (3x²) + (2x) + (-12x) + (-8)

⇒ 3x² + 2x - 12x - 8

⇒ 3x² - 10x - 8

3x² - 10x - 8 = 3x² - 10x - 8 (Yes!)

<u>Option B</u>

⇒ (3x - 4)(x - 2)

⇒ (3x × x) + (3x × -2) + (-4 × x) + (-4 × -2)

⇒ (3x²) + (-6x) + (-4x) + (8)

⇒ 3x² - 6x - 4x + (8)

⇒ 3x² - 10x + 8

3x² - 10x - 8 = 3x² - 10x + 8 (No!)

<u>Option C</u>

⇒ (3x - 4)(x + 2)

⇒ (3x × x) + (3x × 2) + (-4 × x) + (-4 × 2)

⇒ (3x²) + (6x) + (-4x) + (-8)

⇒ 3x² + 6x - 4x - 8

⇒ 3x² + 2x - 8

3x² - 10x - 8 = 3x² + 2x - 8 (No!)

<u>Option D</u>

⇒ (3x - 2)(x - 4)

⇒ (3x × x) + (3x × -4) + (-2 × x) + (-2 × -4)

⇒ (3x²) + (-12x) + (-2x) + (8)

⇒ 3x² - 12x - 2x + 8

⇒ 3x² - 14x + 8

3x² - 10x - 8 = 3x² - 14x + 8 (No!)

Since the expression of option A has the same value as the given expression, option A is correct.

Can someone solve this for me?
Naya [18.7K]

Answer:

-1/2

Step-by-step explanation:

Slope is defined as change in x/change in y.

The x changed by 1/8-(-1/4)=3/8 and the y changed by -4-(-1/4)=(-3/4).

Now, divide the 2 fractions:

(-3/4)/3/8 = -3/4*8/3 = -4/8 = -1/2
