<span>LJK = KJM
-10x +3 = -x + 21
-10x + x = 21 - 3
-9x = 18
x = -2
KJM = -x + 21 = 2 + 21 = 23
LJM = LJK + KJM
LJM = 23 + 23
LJM = 46º..
i think thats how its done </span>
Answer:
D. 2x^2 - 2x + 2
Step-by-step explanation:
(3x2 – 2x + 5) – (x2 + 3) add or subtract like terms
3x^2 - x^2 - 2x - 3 + 5 = 2x^2 - 2x + 2
No. If you write it out, it would be -8*5 which is -40. (-40)^3 is -64000. So your answer would be -64000x
Answer:
(17 + 4)/4
Step-by-step explanation:
"of the sum of 17 and 4" = 17 + 4
"1/4 of"... = 1/4
Put the two expressions together:
1/4 * (17 + 4)
(17 + 4)/4 is your answer.
~
small number = x and large number = 2x + 9
x + 2x + 9 = 2(2x + 9 - x)
3x + 9 = 2x + 18
x= 9
2(9) + 9 = 27
Small number = 9 and large number = 27
