Answer:
3) 3k+20
4) 4+2d
Step-by-step explanation:
You first have to distribute by multiplying the number next to the expression in the parenthesis. Then you combine like terms.
3) 5(k+4)-2k
Step 1: (5×k= 5k) (5×4=20) equation is now 5k+20-2k
Step 2: 5k-2k=3k since they both have the same variable you combine like terms. Equation is now 3k+20 (Final answer)
4) 2(3+d-1)
Step 1: (2×3=6) (2×d=2d) (2×[-1]=2) Equation is now 6+2d-1.
Step 2: (6-2=4) Since both 6 and 1 don't have any variable their like terms and you combine them. Equation is now 4+2d (Final answer)
5(k+4)-2k
Multiply the k and the 4 by 5
Now you have 5k+20-2k
Minus 2k from 5k
Now you have 3k+ 20 that’s the answer
2(3+d-1)
Multiply 3, d, and 1 by 2
Now you have 6+2d-2
Minus 2 from 6
Now you have 4+2d that’s the answe
