Answer : 
Given expression is 
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term
Here coefficient of middle term is -7
Half of -7 is 
Square of is 
=
So the expression becomes ![x^2 - 7x + [tex] \frac{49}{4}](https://tex.z-dn.net/?f=%20%20x%5E2%20-%207x%20%2B%20%20%5Btex%5D%20%5Cfrac%7B49%7D%7B4%7D%20%20)
that gives perfect square trinomial
Hence , the value of 'c' is
Answer:
45 degrees
Step-by-step explanation:
AOB = 140°
and an the angle bisector(OC) is a line which will divide AOB into 2 equal angles
which is 140÷2= 70
and if AOD = 25 then COD= 70-25
= 45 degrees
hope it helps
Answer:
D, 6500 increased by 1.4% is 6591 plus another 1.4% which is 6683 and for the last year you add another 1.4% to get the final answer which is D 6,776.84
To multiply a whole number by a fraction less than one, you have to rewrite the whole number in the expression as a fraction by putting a one under it.
For example, in 10 x 2/5, you would rewrite the 10 to 10/1 x 2/5.
Then, you would multiply the top and bottom of the two fractions. In this case, it would be 10 x 2 and 1x5. This would result in 20/5.
Finally, you would simplify this fraction by dividing. The final answer is 4.
