Answer:
C) 2*18, 3*12, 4*9, 6*6
Step-by-step explanation:
When these number sets are multiplied, all of them equal 36, therefore C is your answer.
Hope this helped! :)
Answer:
a=2
Step-by-step explanation:
12a - 5 = 4a + 11
Subtract 4a from each side
12a-4a - 5 = 4a-4a + 11
8a -5 = 11
Add 5 to each side
8a -5+5 = 11+5
8a = 16
8a/8 = 16/8
a =2
D. 75 cm
Step-by-step explanation:
fill in the y with 20.5, so you get 20.5=0.3x-2. Add the 2 to the 20.5 so you get 22.5=0.3x. Divide both by 0.3 to get 75=x.
sorry if it's a bd explanation, hope this helps :)
You can use a tangent:
We have opposite = 17 and adjacent = x.
substitute:
cross multiply
multiply both sides by √3
divide both sides by 3
Use the Pythagorean theorem:
-------------------------------------------------------------------------------------------------
Other method.
triangle.
The sides are in the ratio 
Therefore
100 times 100
When you want to multiply 100 by 100, count up all the zeros first.
There are 2 zeros in one 100 and 4 zeros in two 100's.
Since there are 4 zeros, that means 100 • 100 is a 1 followed by 4 zeros.
This means 100 • 100 = 10,000
100 multiplied by 100 is 10,000 (ten thousand)
