The length of the dollhouse room is 156. Because you take the 1248 and divide by the 8. Which then gives you 156. To verify this answer, you would multiply 156 by 8 and you should get the answer 1248. so the length of the room is 156.
Step-by-step explanation:

First equation: Your equation is given.
Second equation: Distribute by multiplying every number in the parentheses by the number outside it.
3rd equation: Combine like terms by adding 4x to both sides.
4th equation: Combine like terms by subtracting 14 from both sides.
5th equation: Divide both sides by -2, the coefficient of x.
Subtract the right side and you have
x² -10x -6 -2x -1 = 0
x² -12x -7 = 0
This corresponds to the selection ...
C. x² -12x - 7 = 0
Answer:
Yes, Chris will score
Step-by-step explanation:
Given the function :
F(x) = - 0.05(x - 16)² + 11
Distance from goal = 25
Height of goal = 8
Scoring condition, if ball isn't blocked :
If the ball travels a distance of 25 feets towards goal and elevation of ball isn't greater than 8 feets, then Chris will score ;
Function which models ball height with respect to distance, x
Put x = 25 in the equation and se if f(x) < 8 feets
F(25) = - 0.05(25 - 16)² + 11
F(25) = - 0.05(9)² + 11
F(25) = - 0.05 * 81 + 11
F(25) = - 4.05 + 11
F(25) = 6.95 feets
Hence, Chris would score if ball isn't vlaocjed by DeShawn because the height of ball is lower than the height of the goal.
