Answer:
Step-by-step explanation:
let x and y be length and width of rectangle.
Perimeter=2(x+y)
area=xy
2(x+y)=1/2 xy
4(x+y)=xy
4x+4y=xy
x y-4y=4 x
y(x-4)=4 x

Answer:
188 units cubed
Step-by-step explanation:
The values are x= -2 and x =4 of the given function f (x) =-5|x+1| +3
<h3>What is function?</h3>
Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
According to the question,
The given function is

Here f(x) = -12
Substitute f(x) and solve for x

By subtracting 3 on both sides


By dividing -5 on both sides

We get absolute values for the function.

By subtracting 1 on both sides

Therefore, the values of x are 2 and - 4 of the given function f (x) =-5|x+1| +3

Volume of the cone = 1/3 pi r^2 h = 1005.31 cm^3
Volume of the sphere = 4/3 pi r^3 = 463.25 cm^3
Volume of remaining portion of the cone = 1005.31 - 463.25
= 542.1 cm^3 to nearest tenth
Answer:
Proving an identity is very different in concept from solving an equation.
Step-by-step explanation:
because it Though you'll use many of the same techniques, they are not the same, and the differences are what can cause you problems.
