Answer:
9
Step-by-step explanation:
x^2+6x+9
Is perfect since
(x+3)^2 is perfect square
Identity Is (x+y)^2=x^2+2xy+y^2
Answer:
h(4z)=4+12z / 5+4z
Step-by-step explanation:
The function h is defined by h(x)=4+3x over 5+x
This can be written as
h(x)=4+3x / 5+x
The value of the function at any time depends on the value of x. x is the independent variable. The variable,x can take any value at any time.
To find h(4z), it means that x is taking the value of 4z.
We will substitute 4z in the place of x in the function. This becomes
h(4z)=4+3×4z / 5+4z
h(4z)=4+12z / 5+4z
Answer:
That is 4
Step-by-step explanation: First you need to substitute 9 in for m. Then multiply 4 x 9 to get 36. Then the square root of 36 is 6. Lastly 6-2 equals 4.
Answer:
x = 8.12
Step-by-step explanation:
36+x^2 = y^2
121 + x^2 = z^2
z^2 + y^2 = 289
(121+x^2)+(36+x^2) = 289
157 + 2x^2 = 289
2x^2 = 132
x^2 = 66
x = 8.12
