Evaluate and simplify the expression when c=1 and d=3. 3(2c + d) - 4(c-d) + d2 = [?]

Step-by-step explanation:

3( 2c + d) - 4( c - d) + d²

when

c = 1

d = 3

Substitute the values of c and d into the expression and solve

That's

3[ 2(1) + 3 ] - 4( 1 - 3) + 3²

= 3( 2 + 3) - 4( - 2) + 9

= 3(5) + 8 + 9

= 15 + 17

We have the final answer as

Hope this helps you

answer: h

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
