Answer:
x² +11x +28
Step-by-step explanation:
(x +4) (x+7)
take the first x and multiply by x and then the 7 which gives you x² +7x
then take the 4 and multiply it by the x and the 7 which gives you 4x + 28
add all like terms
The 3 consecutive numbers are 88, 89, and 90. So 90 is the answer.

Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
