Answer:
Step-by-step explanation:
The tick marks you see on the sides denote congruence. If they have the same number of tick marks, then their side length are congruent.
And, recall that congruent side lengths have the same measure.
So, look at the sides with 2 tick marks. They are congruent. Therefore:
Subtract x from both sides:
Subtract 5 from both sides:
So, x is 7.
Now, look at the sides with only 1 tick mark. Again, they are congruent. Thus:
We already know x is 7. So:
Add:
Add 4 to both sides:
So, y is 16.
Answer:
Step-by-step explanation:
We do not add the triangles in because they are the bases and the bases do not get added in the lateral surface areas.
From left to right
Rectangle 1
A = lw = 9.9 *20 =198
Rectangle 2
A = lw = 6.8 *20 =136
Rectangle 3
A = lw = 9.9 *20 =198
Add them together
198+136+198
532
LSA = 532 yds ^2
Use the calculator to graph the function y = 
In the graph , the coordinates of the vertex is the turning point of the graph.
Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.
There will be only one turning point for parabola
Turning point is the vertex
To find vertex we use formula x= 
y =
a=2, b= 35
= -6.25
Now plug in 
in f(x)
Take common denominator
= -75.125
So coordinates of turning point is (-6.25, -75.13)
The graph is attached below.
For each square root, you can simplify the expression under the root as
So we have
This means [1] = 4 and [2] = 
.
