I need help plz help
Sunny_sXe [5.5K]

answer is C. 252 ft^2

split the figure into two pieces and first figure out the rectangle (shown in turquoise).

If you multiply the width and length (18*6) you should get 108.

Then figure out the trapezoid (in magenta). the formula is (a+b)/2*h where a and b are the bases and h is the height. the bases are given, 6 and 18. to find the height, subtract the entire figure's height by 6, which is 18-6 and gives us 12. so the formula converted to this problem is (6+18)/2*12. simplify parenthesis and get 24/2*12. 24/2=12, so multiply 12*12. The area of the trapezoid is 144. Add the areas of both figures together and get 252.

Amber and her friend Nathan are
Gnesinka [82]

Answer:

{(12-4) + (15-8)}x  = 65

Step-by-step explanation:

The amount Amber earns per week

12-4

The amount Nathan earns per week

15 -8

The total amount per week they earn together

(12-4) + (15-8)

Multiply by x weeks

{(12-4) + (15-8)}x

Set this equal to 65 to be the amount they need to equal 65 dollars

{(12-4) + (15-8)}x  = 65

Triangle ABC is reflected over the y-axis. What are the coordinates of the reflected triangle?
Pachacha [2.7K]
Well...you haven't given any values,but:

When a point is reflected over the y-axis, the signs of the x-coordinates are reversed while the signs of the y-coordinates remain the same.

Example:

Let's say point A is (3,5). When you reflect it over the y-axis, it becomes (-3,5).

Hope this helps!
