Step-by-step explanation:
f(-1)=3×(-1)²-4×(-1)
=3×1-4×(-1)
=3+4
=7
hope it helps.
The length of one of the remaining sides is 34.20 meters.
<h3>What is the length?</h3>
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Perimeter of an isosceles trapezoid = sum of lengths of sides of a trapezoid
length of shorter base + length of longer base + (2 x legs)
108 = 11.5 + 28.1 + (2 x legs)
108 = 39.60 + (2 x legs)
108 - 39.60 = (2 x legs)
68.40 = (2 x legs)
leg = 68.40 / 2
= 34.20 meters

Vertically opposite angles are equal.
So,
(11y - 36)° = 63°
=> 11y - 36 = 63
The answer should be 3/16
