The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.
Answer and Step-by-step explanation:
Area (A) = 153
Length (l) = 8 + w
Width (w) = w
A = lw
153 = (8 + w)(w)
153 = [tex]w^{2} + 8w[/tex]
0 = [tex]w^{2} + 8w[/tex] - 153
[tex]w^{2} -9w + 17w - 153[/tex]
(w - 9)(w + 17)
w = 9
w = -17
We can't have a negative length, so we only use 9.
w equals 9.
That means l equals 17 (9 + 8 = 17).
Length = 17
Width = 9

To find the square root of a number, you must divide the number by 2.
True
False
Answer:
False
Step-by-step explanation:
When you are squaring a number, you multiply the number by itself (7*7 or 12*12), so if you were to reverse that and find the square root of the number (let's say 49), you'd have to do some guess and check and figure out which number, when multiplied with itself, would equal that number (7*7 = 49).
The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False.
What is a number system?The number system is a way to represent or express numbers.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number b.
Consider the number 9.
The square root of it is given as,
√(9) = 3
Now, if we multiply 3 by 3 then we get 9 as,
3 x 3 = 9
If we divide 3 by 2 then 3/2 = 1.25 is not 9.
Hence "The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False".

Solve the system of equations using elimination. How many solutions does the system have?
15j + 12k = 18
5j + 4k = 6
Responses
A. One solution, j = 3, k = 3
B. No solution
C. One solution, j = 10, k = 8
D. Infinitely many solutions
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:
0=0
Answer:
Infinitely many solutions

Lebron James's Free Throw % is 75%
What is the probability that he makes 6 Free Throws in a row?
Answer as a decimal rounded to 2 places.
Answer: 0.18
Step-by-step explanation:
From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:
= 75% × 75% × 75% × 75% × 75% × 75%
= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4
= 729/4096
= 0.18
