Answer:
C (x+2)(2x+3)
Step-by-step explanation:
You can count in the picture that in the top part there are two x's (2x) and three ones (3). So the top would be (2x+3)
On the left side there is one x (x) and two ones (2). It would be (x+2).
So combine them together, it would be (x+2)(2x+3).
C.
Answer:
The positive value of will result in exactly one real root is approximately 0.028.
Step-by-step explanation:
Let , roots are those values of so that . That is:
(1)
Roots are determined analytically by the Quadratic Formula:
The smaller root is , and the larger root is .
has one real root when . Then, we solve the discriminant for :
The positive value of will result in exactly one real root is approximately 0.028.
First, separate the x's and the numbers:
+2x and -x
+3 and +5
Next, solve those sums:
+2x - x = 1x = x
+3 +5 = 8
Answer: A. x+ 8
1/8 is least,3/4second,3/16 great
Answer:
1260
Step-by-step explanation:
Round 0.65 to 0.7 and round 1754 to 1800. To get 1260, I recommend an easy way to do this. I would take 18 and multiply it by 7, giving us 126. Because it was supposed to be 0.7, not 7, we multiply by 10 because 7/10 is 0.7. This gives us 126 times 10 which equals 1260.
