Answer: Terms that have identical variable parts (same variable(s) and same exponent(s)). So in this case the like terms are -7q and 9q AND 2 and 6 are like terms *REMEMBER: constant (which are numbers with NO variables can also be like terms)

but to solve this:

first group the like terms so:

(-7q+9q) that gives us 2q

(2+6) that gives us 8

*In your FINAL answer ALWAYS put the number(s) with variables first so the final answer is 2q+8

Find the missing variable for a tralezoid. A=68^2 b= h=4 B=21

Bezzdna [24]

The answer is: " 2291 units " .
____________________________________________
Explanation:
____________________________________________
Formula for "Area of a trapezoid" :
____________________________________________
Area = (1/2) * (base length 1 + base length 2) * height;

or: A = (1/2) * (b + B) * h.

We are missing the value for "b" one of the base lengths.

However, since: A = 68² (given) ; B (the other base length) = 21; and the perpendicular height, "h" = 4 ; we can plug this values into the formula, and solve for "b" ;
________________________________________________
A = (1/2) * (b + B) * h ; ↔ 68² = (1/2) * (b + 21) * 4 ;

↔ 4624 = 2 (b + 21) = 2b + 42 ;

 ↔ 4624 = 2b + 42 ;

 ↔ 2b + 42 = 4624 ;

Subtract "42" from each side of the equation:

 2b + 42 - 42 = 4624 - 42 ;

to get: 2b = 4582 ;
___________________________________________________
 Now, divide each side of the equation by: "2" ; to isolate "b" on one side of the equation; and to solve for "b" ;
___________________________________________________
 2b / 2 = 4582 / 2 ;
___________________________________________________
to get: b = 2291 units.
