5 feet and 3 inches, 1 foot=12 inches, 12×5=60+3=63×5=315. so your answer is 315
There’s not actually a question. But I might be able to help if u show the full problem
Answer:

Step-by-step explanation:
we have

Remember that
To predict a value for y, when x = 4
substitute the value of x in the equation
so

Step-by-step explanation:
base^ans=number attatched to the log
Answer:
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Step-by-step explanation:
To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.
The sum of the polynomials is:
A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2
A + B = 4x^2 + 2x + 3y - 7z
So, the coefficients are:
coefficient of x^2: 4
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
