So we have 80+5=85.
Now let's rewrite the problem. 10*85*6-1.
I put the * sign because when you have a number like this: (10+5)1 It means you will subtract it by the number outside of the parenthesis. Now we need to move onto multiplication because there are no exponents so we skip that.
Lets multiply from left to right.
So we have 10*85*6-1 so lets start with 10*85=850
Now we have
850*6-1 So let's do 850*6=5100
Now 5100-1=5099
So your answer is 5099
(a-25b)(a+4b)=0
Use the quadratic formula or complete the square by looking at the factors
You need to break it down to the common multiples. For 27 it’s 9,3. 9 can also be divided by 3. Now you are left with the number 3
Answer:
135 degrees
Step-by-step explanation:
Octagons have 8 sides which make up 8 angles that are all equal to each other.
The angles must sum up to 1080 degrees in an octagon.
Take 1080 degrees and divide by 8 angles and you will get 135 degrees.
