Um what if you multiply 2.5 x5=12.5 then multiply 16x3=48 and then subtract 12.5 by 48 and you will get 77 cups of sugar srry if it is not the right answer this is not my account this is my fathers im not in collage im in 5th grade . so i hope this helped you
Answer: C. 42
Step-by-step explanation:
(3x + 3) is the same angle as 129.
So, you have to equal them to each other.
3x + 3 = 129
Now you solve.
Subtract 3 from each sides.
3x = 126
Divide 3 from each side.
x=42
Answer: <u>96</u> sq ft.
Step-by-step explanation:
First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.
A = L * W
A = (10 ft) * (3 ft)
A = 30 ft²
30 ft² * 3 = 90 ft²
Next, we will find the area of the two triangles.
A = 
A = 
3 ft + 3 ft = 6 ft²
Lastly, we will add them together for the total surface area.
90 ft² + 6 ft² = 96 ft²
(x+1)²+(y+1)²=9
the answer can be found with
(x-h)²+(y+k)²=r²
where the point (h,k) is the center.
