Answer:
11
Step-by-step explanation:
By this logic, if you are simply placing the numbers side by side to make a new number, it would be 11.
Answer:
True
Step-by-step explanation:
Answer:
–3 and –3
Step-by-step explanation:
x² + 6x = – 9
Rearrange
x² + 6x + 9 = 0
Multiply the first term i.e x² and last term i.e 9 together. The result is 9x².
Next, we shall find two factors of 9x² such that when we add them together, the result will be the same as the 2nd term i.e 6x in the expression above.
The factors are 3x and 3x.
Next, we shall replace 6x with 3x and 3x in the equation above as shown below:
x² + 6x + 9 = 0
x² + 3x + 3x + 9 =0
Factorise
x(x + 3) + 3(x + 3) = 0
(x + 3)(x +3) = 0
x + 3 = 0 or x + 3 =
x = – 3 or x = – 3
Therefore, the solutions are –3 and –3
Answer:
I think you just plug in the first equation to the or the second to the first, it’s actually does not matter. After that you just solve it. For example: we have two equations.
y=11-2x
y=x+2
We just plug in the first equation to the second one.
11-2x=x+2
-3x=9
x=-3. So this is the answer. Hope this helps.
Step-by-step explanation:
Prime numbers are numbers that can only be divided by 1 and itself (like 3,5,7)
