Answer:
6
Step-by-step explanation:
4(6) - 7y = -18
24 - 7y = -18
-7y= -42
y= 6
Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
Answer:
Answer: B, 6/11
Step-by-step explanation:
<em>Well we know that 3+2+1=6+3=9.</em>
<em>So that means we will add the 2 brown crayons to the denominator.</em>
<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>
<em>6/11 is also the smallest number that you can get.</em>
<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>
<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>

Summarizing the question,
Principle(P)=$100
Rate (r)=12%=0.12
Amount (A)=3×P=$300
Time=t=?
n=no of times the interest is compouned per year=4
Then,
A=P{(1+r/n)}^(n×t)
or,300=100×{1+0.12/4}^(4×t)
or,300/100=(1+0.03)^(4×t)
or,3=1.03^(4×t)
Taking log on both sides,
log3=log[(1.03)^(4×t)]
or,log3= (4×t)×log(1.03)
or,4t=log3/log(1.03)
or,t=log3/[4×log(1.03)]
or, t=9.29175...
t=9.3 years ANS!!!
