The answer is 3600
If x is -20, you do -20 to the second power minus 110 multiplied by -20 added by 1800.
Times the price of the model cars to the amount bought.
$15×6= 90.
Lea paid 90 dollars for the model cars.
Now, multiply the price of the paint to the amount bought.
$11×4= 44.
Lea paid 44 dollars for the paint.
Add both together. 90+44= 134.
Therefore, Lea paid $134 for the model cars and paint all together.
hope this helps!
Answer:
78.0 ft
Step-by-step explanation:
pythagoras theorem =
a² + b² = c²
a² + 36² = 85.9²
a² + 1296 = 7378.81
a² = 7378.81 - 1296
a² = 6082.81
a = √6082.81
a = 77.992....
so, a (rounded) = 78 ft :)
X=0 hope this helps let me know
