=3y+18y-12=2y-2-7
=21y-12=2y-9
=21y-2y=-9+12
=19y=3

Answer:
The area of the counter that Carlos will wall tile is 
Step-by-step explanation:
to solve this, we will calculate the area of the counter and the area of the rectangular hole that Carlos would have to leave out for the sink, and then subtract them to get the area that will be tiled.
Total area of the rectangular counter = length X breadth = 
area of the rectangular cut out for the sink = length X breadth =
Surface area that Carlos is meant to tile = 
Hence,the area of the counter that Carlos will wall tile is 
Answer:
B. 3.39 m
Step-by-step explanation:
r² = A/π
= 36/3.14
= 11.465
r = √11.465 = 3.39
Answer:
b. set of real numbers R Superscript m is completely determined by its effect on the columns of the n times n identity matrix.
Step-by-step explanation:
A linear transformation T can be defined as a set of real numbers Rn → Rm is completely determined by its effect on columns of the n × n identity matrix because:
1. The standard matrice's column for the purpose of linear transformation from row Rn to Rm can be termed as the images of columns of the given n x n identity matrix.
2. The standard matrice's column is the basis vector in row Rn. As we know that we can express any vector as a linear combination of these and T is expressed as a linear transformation.
Hence, the true option is (b)
