This is the equation
185+185(2)+185-50
185+370+185-50 (you multiply 185 times 2 first)
370+370-50 (you add 185 to 185)
740-50 (you add 370 to 370)
740-50=690
There were 690 visitors during these three days.
Answer:220
Step-by-step explanation:Simplify
Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = - 
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = -
= - 1
Equation of axis of symmetry is x = - 1
The length of the purple trim needed to outline the given pennant is (5x - 30) cm.
Step-by-step explanation:
Step 1:
To determine the length of purple trim needed to outline the given pennant we determine the perimeter of the triangle.
The perimeter of a triangle is the sum of the individual side lengths.
For the given triangle, the side lengths are
cm,
cm, and
cm.
The perimeter is the sum of these three sides.
Step 2:
The perimeter of the pennant
cm.
The length of the purple trim needed to outline the given pennant is (5x - 30) cm.
