Answer:
<u><em>5.25 inches or </em></u>
<u><em> inches</em></u>
Step-by-step explanation:
<u><em>I believe that the question is what do they multiply to..? If so, we start by </em></u><u><em>making them both in decimal form:</em></u>
<u><em>7 / 2 = 3.5</em></u>
<u><em>3 / 2 = 1.5</em></u>
<u><em>Now, we </em></u><u><em>multiply</em></u><u><em>:</em></u>
<u><em>3.5 * 1.5 = 5.25</em></u>
<u><em>If you want fraction form, we can turn .25 to 1/4.</em></u>
<u><em>Fraction form: </em></u>
4 and 2 since 6+2 is 8 and 8 has two factors which are 4 and 2.
Angle A is 2x + 3
Angle B is 4x + 2
Angle C is 2x - 1
The three angles add up to 180
So:
2x + 3 + 4x + 2 + 2x - 1 = 180
Combine terms
8x + 4 = 180
Subtract 4
8x = 176
x = 22
Now we solve for the angles:
Angle A is 2(22) + 3 = 44 + 3 = 47
Angle B is 4(22) + 2 = 88 + 2 = 90
Angle C is 2(22) - 1 = 44 - 1 = 43
Quick check: 47 + 90 + 43 = 180

Step-by-step explanation:</h3>
Functions are a set of points that show how dependent variables change through independent variables.
Defining a Function
In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.
For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.
Graph of a Function
Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.
Step-by-step explanation:
Let the breadth (b) of a rectangle be x
Then Length (L) = 2x
Now
Perimeter of the rectangle = 15 inches
Or, 2(L + b) = 15
2 ( 2x + x) = 15
2* 3x = 15
6x = 15
x = 15 / 6
x = 2.5 inch
Also Now
Length (L) = 2*2.5 = 5 inches
Breadth (b) = 2.5 inches
Hope it will help :)
