Answer:
the answer is 30
Step-by-step explanation:
because it is an equilateral triangle all sides are the same so if you set 3x+15 equal to 7x-5 and solve for x you get 4x=20 and x= 5
when you plug 5 in to each equation you get 30 for both sides and so it proves that the answer is 30
Answer:
-5
Step-by-step explanation:
Here is how you solve this problem:
First, you set it up like this: 2x+1-3x+2
Second:You are finding f(4) and g(4) so you just plug in 4 for both problems:
2(4)+1-3(4)-2= 9-14= -5
9x2=18) 9x3=27) 9x4=36) 9x5=45) 9x6=54) 9x7=63) 9x8=72) 9x9=81) 9x10=90) Multiples of 9. Now it says 9 more than twice a number so you could do like 24 + 24 = 48 + 9 = 57 Now just do that for what ever problem you have just add the numbers together and add 9! Hope this helps! ;D
