Answer:
4
Step-by-step explanation:
The correct option is 4.
Put 4 in the missing term because 4 is a perfect square and it satisfies the given expression:
4x2 + 40x + 100
Now multiply the 1st term coefficient with 100
4 *100 = 400
Now find two numbers whose product is 400 and whose sum is 40
20*20 = 400
20+20 = 40
Therefore 4 is the correct missing coefficient because it satisfies the expression:
Thus the correct option is 4....
Answer:
x = 5
y = 3
Step-by-step explanation:
substitute x-2 for y in the other problem
X = 17-4(x-2) do your substituting and get x = 5
now you have x plug it into y = x-2
y = 5-2
y = 3
