Answer:
The expression is equivalent , but is not completely factored
Step-by-step explanation:
A student factors 3x² – 12 to the following. 3(x² – 4)
3x² – 12 is equivalent to 3(x² – 4), because 3 was factored out;
If we multiply by 3 by opening the brackets then we get the same expression 3x² – 12.
However; <em>3(x² – 4), could be factored further;</em>
<em>To get; 3(x + 2)(x - 2) ; since x² – 4 is a difference of two squares;</em>
<em>Therefore;</em>
<em>3x² – 12 = 3(x² – 4) = 3(x + 2)(x - 2)</em>
The least is 2/7 then 1/2 then 5/6 and the greatest is 4/2
Hi,
I want to answer yr question, that is our earth. Is that right.
The value of c would have to be an odd integer because an odd integer minus an even integer (8) is always an odd integer. If you are looking at answer choices, the answer will probably the odd integer. (I don't know what your answer choices are. You said which of the following, so there are probably answer choices.)
Answer:
A triangle equals to 180. Given that it is a right triangle, one angle should be 90.
So, 90+20 = 110
180-110= 70
Therefore, the other two angles are 90 and 70.
