Simply put the negative numbers cancel each other oout in terms of the negative sogns therefore the product is indeed postive. Hope this is useful.
√(<em>x</em> + 1) + 3 = 0 ==> √(<em>x</em> + 1) = -3
has no real solutions, since the square root cannot be a negative number. But if we were to ignore that for the moment, one might try taking the square of both sides, which gives
(√(<em>x</em> + 1))² = (-3)² ==> <em>x</em> + 1 = 9 ==> <em>x</em> = 8
But this is not a valid solution, since
√(8 + 1) = √9 = 3 ≠ -3
While -3 is a square root of 9, we had started off with the *positive* square root of <em>x</em> + 1.

Answer:
132 m²
Step-by-step explanation:
The rectangle is 20 m by 6 m.
Base of triangle: 20 m - 8 m - 6 m = 6 m
Height of triangle: 10 m - 6 m = 4 m
The triangle has a base of 6 m and a height of 4 m.
A = LW + bh/2
A = 20 m × 6 m + (6 m × 4 m)/2
A = 120 m² + 12 m²
A = 132 m²
