Answer: Breadth = 11 ; Length = 8
Step-by-step explanation:
Let the width of the rectangle be 'x'
Length of the rectangle = x - 3
Perimeter of the rectangle = 38
Perimeter of rectangle formula = 2 ( length + breadth )
Substitute:
2 ( x + x-3 ) = 38
2 ( 2x - 3 ) = 38
2x - 3 = 19
2x = 19 + 3
2x = 22
x = 11
Therefore, the breadth = 11
Length = x-3 = 11 - 3 = 8
To check, find the perimeter:
2( 11 + 8)
= 2 ( 19 )
= 38.
We get the same perimeter so the answer is correct.
Answer:
length =8
Step-by-step explanation:
x= width
x-3(3 inches less than the width)
x+x-3+x+x-3=38
4x-6=33. add 6 on both sides
4x=44 divide by 4
x=11. plug 11 in for x because 11 is the width. in the equation x-3. (x=width) 11-3= 8. The length is 8.
For the polynomial P (x) = 4x³ + cx² +x + 2 the value of c is -13.
Polynomial is an algebraic expression that has more than two terms. In other words, it is a combination of different variables with mathematical operations.
The given equation of polynomial is,
P (x) = 4x³ + cx² +x + 2 (1)
Since, When polynomial is divided by x-2, and x+1 it gives the same remainder,
This implies that at x=2 and x=-1, the value of the polynomial will be equal.
P(2)=P(-1)
4×(2)³+c(2)²+2+2=4×(-1)³+c(-1)²+(-1)+2
32+4c+4=-4+c+1
3c=-3-36
3c=-39
c=-13
So, the value of c is -13.

First, subtract the estimated tickets that will be sold from the actual tickets sold. 200 – 224 = -24, ignore the negative sign, so the error is 24. Then, divide the error by the actual ticket sold, 24/224= 0.1071 and multiply the answer by 100 to get the percentage. So, the percentage error is 10.7%.
