It is B 80. Because it is 40 x 2 = 80. Hope thishelped
Answer:
=(x-3)(x+7)
Step-by-step explanation:
To factor the trimonial: , we follow these steps:
Step 1: Multiply the first and last term
Step 2: List out product factors of the term derived above
Step 3: Determine which of the factors sum up to the middle term 4x
The required product is: -3 and 7
Therefore: -3x+7x=4x
Step 4: Replace the middle term by the expression derived in step 3 and factorize.
2. -28
5. -60
8. -135
The answers are above. :)
Given Info: "The dashed triangle is the image of the solid triangle"
So the "before" is the large solid triangle and the "after" is the smaller dashed triangle.
The horizontal side of the solid triangle is 15 units. The corresponding side for the dashed triangle is 3 units. Dividing the two values gives: 3/15 = 1/5 = 0.2
Make this value negative. The reason why is due to the fact that we have a sort of reflection going on as we're scaling down the figure.
So the final answer is -0.2
