Answer:
Step-by-step explanation:
13. -2(4)= -8 14. 6(-5)= -30 15. 3(-5)(2)= -30
16. -12(4)= -48 17. -4(2)^2= -64 18. (-5)^2= -25
19. -5(-3)(4)= =60 20. 13(-5)(2)= -130. 21. 3(-3)= -9
Hope this helps!
Answer: x=9
Explanation: All 3 angles of a triangle add up to 180, so basically the equation is (3x-5)+(7x+5)+90=180.
Then you add your like terms, so 3x+ 7x=10x and -5+5=0, which cancels out. Now we have 10x+90=180, we subtract the 90 from 180 to see what 10x is equal to and we get 90. So 10x=90. We divide 10 from 90 and we get the value of X, which is 9.
