1
Step-by-step explanation: PEMDAS
1. 3 divided by 1/3 = 9
2. 9-9= 0
3. 0+1= 1
hope this helps! :-)
5.04 × 10³
This is the scientific notation.
1856 13,486 13,859
Ants, butterflies, beetles
Just look for the smallest number out of the three and then the smallest out of the two left, like 10,2,20. 2, 10, 20
Answer:
3x^2-4
Step-by-step explanation:
f(x) = 2x² + 3 and g(x)=x²-7
(f+ g)(x) = 2x² + 3 + x²-7
Combine like terms
= 2x^2+x^2+3-7
=3x^2-4
Answer:
80 square feet
Step-by-step explanation:
You can split it into a rectangle and a triangle. The area of the rectangle would be 2 * 16 = 32 square feet.
Next, you need to find the height of the triangle. To do this, you can split the triangle into two right triangles and use the pythagorean theorem to find the height. The dimensions of one of the right triangle is 8 for one of the legs and 10 for the hypotenuse. Using the pythagorean theorem, 8^2 + b^2 = 10^2, which is 64 + b^2 = 100, so b^2 = 36 and b = 6. This means that the height is 6. Now, you find the area of the triangle and you get 16 * 6 / 2 = 48.
Adding the area of the rectangle and the triangle: 32 + 48 = 80
Not sure why that's not an answer choice, I'm fairly confident it's right.
