I am going to show you how easy this is. Once you understand, you will be able to do this forever.
:
Assuming the side of the rectangle are (L) length and (W) width, the perimeter:
2L + 2W = 234
:
"the rectangle is twice as long as it is wide,", the equation for this statement:
L = 2W
:
In the first equation, we can replace L with 2W, then we have
2(2W) + 2W = 234
4W + 2W = 234
6W = 234
Divide both sides by 6
W = 234%2F6
W = 39 meters is the width
:
Remember it said the length is twice the width, therefore:
L = 2(39)
L = 78 meters is the length
:
:
Check this by finding the perimeter with these values
2(78) + 2(39) =
156 + 78 = 234
Answer
1. f - 3/4
2. 62 + h
Step-by-step explanation:
1. 1/4 of the fish are angelfish, all fish are one whole, one whole - 3/4's = 1/4
2. we dont have the value of H so we in turn have to figure out the equation and 62 + h is the only answer we can come to
Answer:
Proportional
Step-by-step explanation:
B ∪ (C' ∩ A)
Starting from the inside, C' ∩ A is the intersection of not C, which is everything except the circle C, and A. That's the part I shaded in bright blue.
That's unioned with B, which is just all of the circle B. I shaded the parts of B that I didn't already shade with a grey-blue.
These should all be the same shade; I just made them slightly different for explanation.
The turning point is known as the vertex when we talk about parabolas. The vertex is either the highest point or the lowest point. In this case, it is the lowest point.
<h3>The graph shows the turning point at (-2, -1)</h3>
-------------------------------------------------------------------------------------------
The term "root" is another term for "x intercept". This is where the graph crosses or touches the x axis.
<h3>The two roots are (-3, 0) and (-1, 0)</h3>
Since the y coordinate of any x intercept is always y = 0, we can state "the roots are -3 and -1" to indicate what is in bold above, just in a shortened way.
Side note: the x coordinate of the vertex is always halfway between the x coordinates of both roots of any parabola. The vertical axis of symmetry passes through the vertex.
