Answer:
#16 is linear but idk what 17 is
With these questions it is asking you to take a common factor
out of each equation.
Let’s take the second question: 19x³ - 38x²
We need to find something that will go
into 19x³ and 38x²
First off, they both contain x so we can
divide them by x. We take the x out and put the rest in brackets, like this:
x(19x² - 38x)
They still have x so we can do that
again.
x²(19x - 38)
Now, does anything go into 19x and 38?
Yes, they are both divisible by 19. So take that out too!
19x²(x - 2)
Nothing more goes into x or 2, so the
problem is solved!
Remember to always take a common factor
out before you try to factorise. (So try question 15 again with this in mind)
You can also check your answer by
expanding it again.
Step-by-step explanation:
AB=OB-OA
AB=[4,-2]-[-4,6]
AB=[8,-8],|AB|=8units
BC=OC-OB
BC=[-6,-4]-[4,-2]
BC=[-10,-2],|BC|=√104
AC=OC-OA
AC=[-6,-4]-[-4,6]
AC=[-2,-10],|AC|=√104
d. Based on the lengths of the sides,the triangle is isosceles
Answer:
4,000,292
Step-by-step explanation:
All you need to do to solve this problem is to know the place values and remember to add place-holders (zeroes) for place values that have no value.
