Answer:
answer: All real numbers, or No solutions
Step-by-step explanation:
okay, the equation says 4(x+4)=(4x+16)
if we apply 4 to the parenthesis we get 4*(x+4)=4x+16
so basically the equation is telling us 4x+16=4x+16, which gives us all real numbers or No solutions as the answer
Answer: 129.81 m, roughly 130 m
Step-by-step explanation: Let me know if you need an explanation.
I did 54/8 because you are multiplying D×8 and the product of 54/8= 6.75 so yeah the answer is 6.75
Answer:
Option b is the correct answer
Step-by-step explanation:
The graph in the picture is the graph of a quadratic equation and it takes the shape of a parabola.
The points on the x axis through which the parabola cuts across is used to determine the solution of the quadratic equation.
Looking at the parabola formed from the plotted points, it cuts the x axis at
x = -1 and x= -2
These are the factors of the equation. To get the equation, we multiply the factors.
x= -1, x +1 = 0
x =-2 , x + 2= 0
The equation is (x+1)(x+2)
Expanding the brackets,
x×x + x×2 +1×x + 1×2
= x^2 + 2x + x +2
= x^2 + 3x +2 = 0
Option b is the correct answer
