The formula is logb x = logd x / logd b
so log4 (x + 2) = log (x+2) / log 4
ITs A
Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
Answer:
8
Step-by-step explanation:
-4-(-12)
If you take away a negative that means you are adding so you do -4+12 because there is a double negative.
The answer is 18 inches.
432 / 24 = 18
area / length = width
