Answer:
x=5 and x=1
Step-by-step explanation:
3 |-3x + 9| = -18
/3 /3
|-3x + 9| = -6
-3x + 9 = -6 -3x + 9 = 6
-9 -9 -9 -9
-3x = -15 -3x = -3
/-3 /-3 /-3 /-3
x = 5 and x = 1
Thats easy
3.2/1.6=y/19
y=(3.2÷1.6)×19=38
Note that 5x appears on both sides of this equation. Delete 5x from each side. This leaves us with 3x = 15/2. Dividing both sides by 3 results in x = 5/2 (ans)
Answer:
Step-by-step explanation:
x²+x²=14²
2x²=196
x²=196/2=98
x=7√2 ft
X(x+2)=255
x²+2x-255=0
(x-15)(x+17)=0
x=15 or x=-17
take the positive number only, so the two consecutive positive odd integers are 15 and 17.
