I'm stuck on how to find the area of these problems. Any help?

Step-by-step explanation:

For the rectangle, the area equation is just length x width. It's just multiplying exponents, too. So just multiply (4x^5)(0.25x^2) and when multiplying exponents, you add them. So you would get x^7

For the triangle, bh/2

Multiply (1.5x^9h^6z)(6x^5h^3z^6)

add exponents of like terms

I got (9x^14)(y^9)(z^7)/2

Also in word form it's nine x to the 14th, y to the ninth and z to the 7th. Divide by two and you divide 9/2 and keep that number with the exponents.

I got 4.5x^14y^9z^7, anyone else? Idk I'm in ap calc and i should be able to do this. if it doesn't work this way, try the FOIL method.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
