Answer:
x = 7
Step-by-step explanation:
The proportion is
14/6 = 21/(3x - 12) Cross Multiply
14*(3x - 12) = 6*21 Remove the brackets and combine
42x - 168 = 126 Add 168 to both sides
42x = 126 + 168
42x = 294 Divide by 42
x = 294/42
x = 7
(x+y)^2=x^2+y^2+2xy=73+2*24=73+48=121
⇒ (x+y)^2=121
Answer:
x>2
Step-by-step explanation:
5-x<2(x-3)+5
5-x<2x-6+5
5-x<2x-1
6-x<2x
6<3x
x>2
1)8
2)3
3)1
4)14
the coefficient is the number in front of the variable
