The first one: The formula for a trapezoid is 1/2 h(b1+ b2) or if you split it up do 1/2 the base times the height on the triangle, then do length times width on the rectangle.
The second one: Just put and imaginary line down the sides of the H leaving the middle. The dimensions of the middle are, 3 by 4. The dimensions of the two sides are 12 by 3. Just multiply length times width, and for the two long sides... multiply by two. You should get 72 for it. Just add twelve to that, and you are good to go!
The area of the cheese is 8 square inches. to find out the sides, you must find the square root of 8. √8 = 2.82.
Answer:
The range is 5.
Step-by-step explanation:
You can deduce this by concluding all other statements are true, or by calculating the range. 10 - 1 = 9
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, - 2) and (x₂, y₂ ) = (9, 3)
m = 
=
Answer:
Option 1
Step-by-step explanation:
12x²+2x-4
2(6x²+x-2)
2(6x²+4x-3x-2)
2(2x(3x+2)-1(3x+2))
2(3x+2)(2x-1)
