−9x (5x+4 ) +10 (x+3) can someone please solve his for me thank u step by step please i really need to find out how to do it

Answer:

-45 $x^{2}$ -26x+30

Step-by-step explanation:

So first you let's divide this equation into three parts.

Part one -9x(5x+4)

Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45 $x^{2}$ and -9x*4 = -36x
Step two: Put the answers together. That would leave us with -45 $x^{2}$ -36x.

Part two 10(x+3)

Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30
Step two: Put the answers together. That would leave us with 10x+30

Part three solve

Step one: combine and put together what you have solved for. That would leave us with a -45 $x^{2}$ -36x+ 10x+30
Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.
Step three: Write the equation in standard form. Therefore the answer is -45 $x^{2}$ -26x+30.

Answer:

Graph attached.

Step-by-step explanation:

In the question the given parameters are as followed.

$y=7cos(\frac{x}{2})+1$

1). Amplitude a = 7

2). Period = $\frac{2\pi }{\frac{1}{2}}=2\pi \times 2=4\pi$

3). Vertical shift = 1 means mid line of the graph will be y =1 and maximum of the graph is 8 and minimum is -6.

12 $x$

Step-by-step explanation:

8 divided by two-thirds of x is

⇒ 8/2/3 × $x$

⇒ 8 × (3/2) $x$

⇒ 8×3 $x$ / 2

⇒ 24 $x$ / 2

∴ 12 $x$
