Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
Vertex = -b/2a = -(44)/2(-1) = -44/-2 = 22
To find the x-intercepts, set the function equal to 0 and solve for x
Answer:
area of P=πr^2
area of Q=πr^2/4=π×400/4=100π
acc to ques
A(q)=4× A(p)
100π=4×πr^2.
100=4r^2
r^2=25
radius of p= √25=5cm
