Answer:
length = (x − 8) units and width = (x − 9) units
Step-by-step explanation:
We need to factor
x^2 - 17x + 72
We need two numbers whose product is 72 and whose sum is -17.
The numbers are -8 and -9.
x^2 - 17x + 72 = (x - 8)(x - 9)
Answer: length = (x − 8) units and width = (x − 9) units
Answer:
A≈9.63
Step-by-step explanation:
Circumference: 11
Using the formulas
A=πr2
C=2πr
Solving forA
A=C2
4π=112
4·π≈9.62887
Answer:
m+m×0.15
because it increased by 15%
you get m's 15% if you multiply it with 0.15
Answer:
32
Step-by-step explanation:
The answer would be 32:);)
Hello!
We can solve this system using substitution.
Since y = -3x + 5, we can substitute this into the following equation:
5x - 4(-3x + 5) = -3
Simplify:
5x - 4(-3x) - 4(5) = -3
5x + 12x - 20 = -3
Combine like terms:
17x - 20 = -3
Add 20 to both sides:
17x = 17
x = 1
Substitute to find y:
y = -3(1) + 5
y = -3 + 5
y = 2
Solution: (1, 2)
