Answer:
14.4 inches
Step-by-step explanation:
Use the Pythagorean theorem: 
So, this will be: 
By simplifying we get:
c = 
The missing side is: 14.4 (rounded to the tenth)
Answer:
b = -2 2/3
Step-by-step explanation:
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 5 from both sides:
-3b + 5 (-5) = 13 (-5)
-3b = 13 - 5
-3b = 8
Next, divide -3 from both sides:
(-3b)/-3 = (8)/-3
b = -8/3
b = -2 2/3

Answer:
<em>h = v/lw .</em>
Step-by-step explanation:
v=lwh
Divide both sides by lw:
v / lw = h.
P = 2(L + W)
L = W + 3
these would be ur equations...and u would sub in 26 for P
Answer:
side x is 5 cm long
Step-by-step explanation:
Use proportions, given that the two triangles are similar because they contain three equal angles:
One angle due to connected by the vertex (oppose by the vertex), another angle as marked with the tick, and the third one has to be the same due to the fact that the addition of the three internal angles of a triangle must equal 180 degrees.
Then our proportion becomes:

And then we solve for x by multiplying both sides by 40 (to eliminate the denominator on the right):
