209 is the answer (if you know how to divide do it)
Answer:
x = 2 and x = -2
Step-by-step explanation:
The easiest way is to guess. We know that you can't have a square root of a negative number. This constrains x between negative infinity to 2. Testing 2 and -2, we see that it satisfy the equation.
The more systematic approach is shown below
x= -2, 2
Answer:
Step-by-step explanation:
Remember the SAS rule is that you know the measure of 2 sides and their angle in between. (Note that SSA side side angle DOESN'T work.) For the first question we know that sides JH and LM are congruent, and sides GJ and MK are as well. Secondly, we know that angles M and J are congruent. The question is; does this problem follow the SAS (side angle side) rule? Yes, their are two proven congruent sides on the two triangles, and the angle between them is proven congruent as well.
Second one is congruent because it follows the SSS rule (side side side) ie: all sides are congruent, so therefore the triangles are congruent.
Think about the third one. Is it congruent or not. (To be congruent it has to follow SSS, or SAS) Comment below so I can correct you.
Answer:
Step-by-step explanation:
So the single blocks are 1, the lines are 10, the single layer is 100 and the blocks are 1000. Let em know if you don't quite get that. But to find how many blocks are there in total we add each part.
1 block + 2 surfaces + 3 lines +6 single little blocks. that's one 1,000, two 100s, three 10s and six 1s or in other words 1,000 + 200 + 30 + 6 = 1,236
