The given expression is 3b x 4c
In this 3 and 4 are the coefficients and b and
c are the variables.
When we multiply the coefficients we get:
3 x 4 = 12
And the product of variables is:
b x c = bc<span>
Now multiply the product of coefficients
and product of variables we get:</span>
12 x bc = 12bc
<span>So 12bc is the answer.<span>
</span></span>
The answer is x <span> ≤ 6, i think</span>
Answer:
= -cot5x
Step-by-step explanation:
sin7x - sin3x = sin(5x + 2x) - sin(5x - 2x)
= [sin5x cos2x + cos5x sin2x] - [sin5x cos2x - cos5x sin2x]
= 2 cos5x sin2x
cos7x - cos3x = cos(5x + 2x) - cos(5x - 2x)
= [cos5x cos2x - sin5x sin2x ] - [cos5x cos2x + sin5x sin2x]
= -2 sin5x sin2x
so
(sin7x - sin3x)/(cos7x - cos3x)
= -cos5x/sin5x = -cot5x
Step-by-step explanation:
By definition, the area of a rectangle is given by:
A = w * lA=w∗l
Where,
w: width of the rectangle
l: length of the rectangle
We then have the following expression for the area:
A = k ^ 2 + 19k + 60A=k
2
+19k+60
What we must do is factorize the expression following the following steps:
1) Find two numbers that are equal to 19
2) Find two multiplied numbers equal to 60
We have then:
A = (k + 15) (k + 4)A=(k+15)(k+4)
Therefore, the width of the rectangle is:
w = (k + 4)w=(k+4)
Answer:
Growth
Step-by-step explanation:
If its multiplied by more than 1.0 its growth, if less, its decay
