Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
Three brass pennies is the short story and the
setting of this story is Ancient Chinese city.
<span>The theme of the story is about desires and
happiness. It is not necessary that what we desire bring happiness in our
lives. Sometimes we think and desire for something that may be it brings
happiness but instead of happiness it causes trouble.</span>
First, the dot stands for the "product". You have to multiply.
5/8* 2/7
= [5/ (2*4)]* (2/7)
= 5/4* 1/7 (because 2 and 2 cancel out)
= (5*1)/ (4*7)
= 5/28
The final answer is 5/28~
Answer:
For the first equation the answer for "X" will be,
if you want me to solve for y instead then the answer will be,
for the second equation the answer for "X" will be,
If you want me to solve for y instead then the answer will be,
