Answer:
5.20 to the nearest hundredth.
Step-by-step explanation:
The altitude line bisects the base of the triangle to form 2 right angled triangles with hypotenuse = 6 and the base = 3.
So, by the Pythagoras theorem the altitude is calculated as follows:
6^2 = 3^2 + x^2
x^2 = 36 - 9 = 27
x = √27
= 5.20 to the nearest hundredth.
Answer:
a = -1
Step-by-step explanation:
Combine like terms 6a + 5a = 11a
11a = -11
Divide -11 by 11
-11/11 = -1
Answer:
-45 < x < 5 (see graph below)
Step-by-step explanation:
to isolate x by itself, subtract 20 from all three terms of the equation:

once you finish subtracting 20, x should be by itself, making the equation graphable:

since x is not equal to -45 or 25, the graph line endings have open circles.
all you have to do is add up all the sides and your answer will be 21 cm
