x^2+6x+9=1
Answer:x=-2,-4
Step-by-step explanation:
140g of liquid A is and 128g of liquid B are mixed to make liquid C
work out the density of liquid C
density is defined as mass per unit volume
in this case liquids A and B with 2 different densities are mixed and we are asked to find the density of the liquid C
liquid A has a density of 0.7 g/cm³
mass of liquid A added is 140 g
therefore volume of liquid A added is - 140 g / 0.7 g/cm³ = 200 cm³
liquid B has a density of 1.6 g/cm³
mass of liquid B added is 128 g
volume of liquid B added is - 128 g / 1.6 g/cm³ = 80 cm³
the total mass of liquid C after adding liquid A and B = 140 g + 128 g = 268 g
total volume in liquid C - 200 cm³ + 80 cm³ = 280 cm³
density of liquid C = mass / volume
= 268 g / 280 cm³ = 0.957 g/cm³
density of liquid C - 0.957 g/cm³
Find m(2)
I have no idea how to do this help me
Answer:
10
Step-by-step explanation:
All this is saying is when there is one x value it is equal to 5
so, applying that logic, 2 fives is equal to 2*5=10
so when x=2, it is equal to 10
Hope this helps you out!!!
