Answer:
1150
Step-by-step explanation:
25x46
= 25x40+25x6
=1000+25x4+25x2
=1000+100+50
=1150

Answer: Choice F) 1</h3>
=============================================
Explanation:
x^2+8x+7 factors to (x+1)(x+7)
x^2+4x-21 factors to (x-3)(x+7)
Therefore, the numerator (x^2+8x+7)(x-3) updates to (x+1)(x+7)(x-3)
The denominator (x^2+4x-21)(x+1) updates to (x-3)(x+7)(x+1)
We have three pairs of terms that will cancel between the numerator and denominator. The (x+1) terms pair up and cancel out, so do the (x+7) terms and also the (x-3) terms as well. Everything cancels out. The only thing left is 1 because x/x = 1 where x is nonzero. We can have a more complicated expression replace x to get the same basic idea. This is what I mean by "canceling".
Answer:
Since, the coordinates of the given triangle are (0,0), (4,-4) and (-4,-2)
In the dilation by the scale factor k with centered at origin,

Thus, If the dilation occurs by the scale factor of 2 with centered at origin,
New coordinates of the triangles are,



Thus, the coordinates of new triangle are,
(0,0) ( -8, 8) and (-8,-4)
