Answer:
The correct answer is 784 square inches.
Step-by-step explanation:
Depth of each shelf made by Alamo is 14 inches.
So the base of the right isosceles triangular supporter is 14 inches.
So one equal side is 14 cm. Now by using Pythogoras theorem we can calculate the other side of the supporter =
= 19.8 inches.
Area of the right isosceles triangle is given by
× base ×height. Here the base and height are equal to 14 inches.
Therefore area of each right isosceles triangular supporter is
× 14 × 14 = 98 square inches.
Each shelf would require two such supporters and there are 4 such shelves. Thus total number of supporters required are 8.
Square inches of wood necessary for 8 right isosceles triangular supporters = 98 × 8 = 784 square inches.
4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x.
2x^2+5x+7
5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3
There you go! Hope it helps

Answer- The one pound package is a better deal because it costs 32 cents per ounce rather than the 20 oz, which charged 45 cents per oz.
Explanation- let’s convert all units to ONE OUNCE. 3.59/20(oz)= 0.45, do 45 cents per ounce for the first. For the second, we know that one pound is 8 oz so divide 2.59 by 8 and you get 32 cents per oz. We know that if we are getting 8 oz for 32 cents per ounce, it is the better deal rather than 45 cents per oz.
Answer:
100,100
Step-by-step explanation:
perimeter=400 m
length=x
let width=y
2(x+y)=400
x+y=200
y=200-x
area A=xy=x(200-x)=200x-x²
