Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x

Therefore, the width is 16 cm, the width is 16*3=48 cm

Answer:
The expression 6x should be 6x^2.
Step-by-step explanation:
Given is the chart of multiplication of the binomial by the trinomial.
Let's check each element in the chart:-
3x times x^2 = 3x^3
3x times 2x = 6x^2
3x times 4 = 12x
2 times x^2 = 2x^2
2 times 2x = 4x
2 times 4 = 8
From the given chart, we can identify that <u>6x should be 6x^2.</u>
Hence. option B is correct, i.e. The expression 6x should be 6x^2.

Step-by-step explanation:
Answer:
lnx/ln4
Step-by-step explanation:
Given
y=4^x
In order to find the inverse of the function the first step is to replace the y with x and x with y
So,
Replacing x with y and y with x
x= 4^y
We have to find the value of y explicitly to find the invers.
The above equation can also be written as:
4^y=x
As the variable is in exponent, to bring it down, ln has to be taken on both sides.
ln 4^y =ln x
The power of will be multiplied with the ln.
y ln4=lnx
y=lnx/ln4
So,
The inverse is lnx/ln4 ..
