Can someone help, please
Wittaler [7]
(5 x 12) ÷ 2 = 30 (area of triangle)
40 x 12 = 480 (area of rectangle)
12 ÷ 2 = 6 (radius of semicircle)
3.14 x 6^2 = 3.14 x 36 = 113.04
113.04 ÷ 2 = 56.52 (area of semicircle)
30 + 480 + 56.52 = 566.52 square feet

Choose the equation that represents the line passing through the point (2,-4) with a slope of 1/2? y=1/2x+5, y=1/2x-3, y=1/2x-5,
LUCKY_DIMON [66]
Correct answer: <span>y=1/2x-5
</span>
given: point = (2,-4)
slope = 1/2 

Explanation: equation of line is: y = mx + c
where, m is the slope
c is the y-intercept

Now, 
here, y = 1/2x + c
put, x = 2, y = -4
we get, -4 = (1/2).2 + c
or c = -4 - 1
or c = -5 

Hence, equation of line is : y = 1/2x-5

andrezito [222]
  • 7a²b+5ab²-4ab²-3ab²+2a²b²

Combine like terms

  • 5ab²-4ab²-3ab²+7a²b+2a²b²
  • (5-4-3)ab²+7a²b+2a²b²
  • -2ab²+7a²b+2a²b²

Two factorisation ways

  • 7a²b-2ab²(1+a)

Or

  • ab(7a-2b+2ab)
