Answer:

distribute the +(positive) 5 to the numbers in the parenthesis (8x-7) and solve it from there! it is left as an expression, because you can't add a variable with an integer

Step-by-step explanation:

5*8x=40x

5*-7= -35

so it's: -9x+40x-35 which also equals 31x-35

Answer: 31x - 35

Let’s start by rewriting the equation

-9x+5(8x-7)

Now let’s distribute

-9x+5(8x-7)

-9x+40x-35

Now we need to combine like terms. These are numbers that share the same variable, or lack of.

-9x + 40x -35

31x - 35

Since there is no equal sign, this is as simplified as this equation can get. If you need more help feel free to comment below :)

If Raj randomly chooses a point in the square below, what is the probability that point is not in the circle? Assume that pi = 3

Answer:

49.7%

Step-by-step explanation:

A cdircle is located within a square.

Area of the circle

Area = $\pi$ $r^{2}$ , where r = 4 units.

Area Circle = 50.3 units^2

Area of the square

Area = l*w or l^2 for a square, since l = w

Area = (10 units)^2

Area = 100 units^2

Area in the square but outside the circle

This is the difference [Square minus Circle Areas]

Square minus Circle Areas = 100 - 50.3 or 49.7 units^2

Probability

The probability of picking a point in the square that is not in the circle is the ration of the two areas: [Outside Circle/Square]x100%

(49.7 units^2)/(100 units^2)x100% = 49.7%

A cylindrical can has a volume of 2in^(3). Express the surface area of the can as a function of its radius,r.

noname [10]

$V=2 \text{ in}^3\\
A=2\pi r (r+h)\\
h=?\\\\
V=\pi r^2h=2\\
\pi r^2h=2\\
h=\dfrac{2}{\pi r^2}\\
A=2\pi r\left(r+\dfrac{2}{\pi r^2}\right)\\
\boxed{A=2\pi r^2+\dfrac{4}{r}}
