Answer: the above stated equation is a quadratic equation
Step-by-step explanation:
Given the following equations
y = x^2 + 5x - 3....equation 1
y-x = 2
y = x + 2........equation 2
Let equation 1 equal equation 2
x^2 + 5x -3 = x + 2
Bringing the equation to one side and equating to zero
X^2 +5x - 3 -x -2 = 0
X2 + 5x -x -3 -2 = 0
X^2 + 4x -5
Solving the aquatic equation
(x + 5)(x -1) = 0
X + 5 = 0
X1 = -5
X- 1 = 0
X2 = 1
To prove:
Substitute the values for x1and x2 into the equation x^2 + 4x - 5 = 0
Answer:
2/52 so the chance is unlikely.
Step-by-step explanation:
well I think I’m right because sometimes when my family has time we play blackjack in my house for fun or another card game so I should be right.
1)
use Pythagoras, so that
the square root if 224 is 14.96662955
so roughly, she needs 15ft for the remaining side.
15+10+18=43
so the answer is c.
2)
first calculate the length through the pond
36^2+49^2=3697
square root of 3697 =60.80296045
36+49=85
85-60.80296045=24.19703955
so he saves about 24.2m
Let
x----------> the number
we know that
x/11=2/5-----> x=11*2/5-------> x=22/5
the answer is
the number is 22/5
