Since a polynomial is where we have like terms such as (1 x 10²) and (4 x 10²), we can add these up using the distributive property to get (5 x 10²) but still keep the 10². For example, it's similar to if we had 2x²+3x²=5x². The x² is still there, but we add up the 2 and 3. Similarly, we can add these up for 10^1 and 10^0
Answer:
Step-by-step explanation:
11 a).
20x + 5 + 24x - 1 = 180
44x = 176
x = 176 / 44
x = 4
b). 6x = 5x + 10
x = 10

Answer:
18√2
Step-by-step explanation:
The area of the smaller triangle is 1/2 that of the larger one. Since the triangles are similar, the dimensions of the smaller triangle are √(1/2) those of the larger one.
36 · √(1/2) = 36 · (√2)/2 = 18√2 . . . . length of line dividing the triangle
Let be the volume of 20% solution, the volume of the 60% solution. We want a total volume of 400 mL in the final mixture, so
Each mL of either solution will contribute a corresponding concentration, and in the final mixture we want the 400 mL to have a 40% concentration, which means we should also have
Solve the system and we get .
