(x - 2 < 5) ∩ (x + 7 > 6)
Let's resolve each one
x - 2 < 5
x < 5 + 2
x < 7
x + 7 > 6
x > 6 - 7
x > -1
So we have 2 conditions: x > -1 and x < 7 plus, we need the values that's equal in x < 7 and x > -1 because we have an intersection
S = {x e R / -1 < x < 7}
Answer:
x=10
Step-by-step explanation:
a^2=b(b+c)
12^2=8(8+x)
144=64+8x
-64 -64
______
80=8x
x=10
