Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.
Try B, but note I’m not sure if right.

Answer:
<h3>
-58, -57, -56</h3>
Step-by-step explanation:
x - the first of consecutive integers
x+1 - the second of consecutive integers
x+2 - the third of consecutive integers
x+x+2 - sum of the first and third integers
3(x+x+2) - three times the sum of the first and third integers
3(x+x+2) = -342
÷3 ÷3
2x + 2 = -114
-2 -2
2x = -116
÷2 ÷2
x = -58
x+1 = -58 + 1 = -57
x+2 = -58 + 2 = -56
