#5,
it says that the angle on top is 221, so you subtract that from 360,
360-221= the rest..... 139
Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139
139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer
Answer:
(a - 3b)(a + 3b)
Step-by-step explanation:
a² - 9b²
(a)² - (3b)²
(a - 3b)(a + 3b)
Answer:
x = 
Step-by-step explanation:
Given
+
= 5 ← combine terms on left side
= 5 ( multiply both sides by x )
8 = 5x ( divide both sides by 5 )
= x
Yes,
Step-by Step explaination:
If the cheetah is going at a faster rate of speed the first run it has a farther distance
So it collects more distance. The slower they run in the short period of time, the less distance they rank up.
Answer:
a)Add the terms in the bottom equation to the terms in the top equation to eliminate y
