Answer:
Step-by-step explanation:
8 + 1/2
How many halves are in 8?
First of all, how many wholes are in 8? 8, obviously, right?
How many halves are in each whole? Two.
How many halves are in 8? 16.
One half is just one half, simple as that.
16 + 1 = 17
So it's 17/2.
I do oki cool how can I help you out:)
Answer: F
Explanation: you already know you have a 90° and the straight lines means it’s 180° so you need to find x and z which are the same so 2x + 90=180 which you would then subtract 90 from 180 which would be 90 then divide 90 by two which would be 45
Yay, love these ones.
First of all, (4x-+3)(-2x-5) is the same as (4x-3)(-2x-5)
So the method for solving these can be remembered by FOIL.
F= Firsts O= Outsides I= Insides L= Lasts
In other words everything is multiplied by everything, for example:
4x * -2x and -3 * -5 <span>is the firsts of the brackets multiplied and last of the brackets mulitplied
</span>
4x * -5 and 3 * -2x is the outsides of the brackets multiplied and the insides of the brackets multiplied
<span>
The SUM of FOIL is then added:</span><span>
</span><em>4x*-2x = -8x^2</em>
<em>-3*-5= 15</em>
<em>4x*-5=-20x</em>
<span><em>3*-2x=-6x</em>
</span><span>-8x^2 -20x -6x + 15 = 0
-8x^2 -26x + 15 = 0
So the factored of (4x-3)(-2x-5) <u /><em>=</em> -8x^2 -26x + 15 = 0
So then you graph that equation on your given grid

A=xy+yz
A=y*(x+z)
y=A/(x+z)
