Answer:
her score would be -22
Step-by-step explanation:
20-42=-22
Answer:
16
Step-by-step explanation:
Shape C is A trapezoid
Area of trapezoid = 
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.
Hence the area of shape C = 16 square units
If you want the area of the entire trapeziod.
The formula for area of a trapeziod is:
1/2h(b₁+b₂)
So the equation applied to the trapeziod is:
2.5(20+12)
20+12 is 32. 32 multiplied by 2.5 is 80.

The side length is 2.24 inches.
The area of a square is given by s²; we have
s² = 5
To find the value of s, we take the square root of each side:
√s² = √5
s = √5 = 2.236 ≈ 2.24
Answer:
x2+3y
Step-by-step explanation Combine like terms y+y+y=x2 3y+x2 and the solution is x2+3y.
