Answer:
Step-by-step explanation:
Information that we know about the square:
side length: which can asol be expressed as:
we can use this information to calculate the area by the formula for the area of a square:
we subtitute the side length:
the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:
The exact value of the area of the square is
ANSWER:9
Step-by-step explanation:
X² - 8x = -10
to have a complete square, we must have this format:
a² + 2ab + b²
a² = x²
2ab = -8x ⇒ 2(x)(-4)
b² = -4² = 16
x² - 8x + 16 = -10 + 16
x² - 8x + 16 = +6
(x-4)² - 6 = 0
Both sides must have an additional value of 16.

1 litre = 1000 ml
1 ml = 1 / 1000= 0.001 litre
150 ml = 150 / 1000 = 0 .15 litre
4 + 0.15 = 4.15 litres
