Do you have a picture if not you just mutilply and get 12 I think
Answer:
Step-by-step explanation:
x^2+20=4 first isolate the variable by subtracting 20 on both sides.
x^2=-16 again isolate the variable but this time you square root both sides.
=
then simplify
x= ±4
Answer:
1958.6
Step-by-step explanation:
2784.95−826.35
=2784.95−826.35
=2784.95+−826.35
=1958.6
First, let's find the area of the semi-circle.
Area of a circle = π*r²
Looking at the rectangle, the diameter for the circle is 2 ft. Since we need the radius though, divide the diameter by 2 to get the radius.
r = 1
A = π * 1²
A = π * 1
A = π
But since it's a semicircle, you need to divide that area by 2.
3.14/2 = 1.57
The area of the semi-circle is 1.57.
Area of a rectangle = lw
l = 2
w = 4
A = 2 * 4
A = 8
The area of the rectangle is 8.
Now add those together to get the area of the entire figure.
1.57 + 8 = 9.57
The figure is about 9.57 square feet.
1 pound = 16 ounces
multiply the amount of pounds you have by 16 (that's how many ounces is in a pound) your answer should be whatever you get
example: you have 13 pounds, just multiply it by 16, the answer is 208.
so there are 208 ounces in 13 pounds.
or you could go google and ask them.
hope this helps.
