Two students write the following expressions to answer an exercise: 7 + 4(5 – 3)2 + and 8 + (5 – 3)24 + 7

a. Simplify the two expressions. List each step you use.

b. Explain the similarities in the steps.

C. Make up another expression that uses the same numbers and operations, but
has a different value. Then simplify the expression, listing each step.

answer: the answer is 127 degrees

c

-by-step explanation:

it would be c

you have orange juice on wednesday. (idk why this is the answer)

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
