Evaluate given: x=2 & y=6 8-4x+5y

30

Step-by-step explanation:

We are given the expression:

and asked to evaluate given x=2 and y=6.

Therefore, we must substitute 2 for x and 6 for y.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Multiply 4 and 2.

4*2= 8

Multiply 5 and 6.

5*6=30

Subtract 8 from 8.

8-8=0

Add 0 and 30.

The expression 8-4x+5y when evaluated at x=2 and y=6 is equal to 30.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
