Answer:
Trapezoid
Step-by-step explanation:
We have been given that Marcus drew a quadrilateral with only 1 pair of parallel sides. We are asked to determine the quadrilateral that Marcus drew.
We know that a parallelogram has two pair of parallel sides.
We also know that rhombus is a parallelogram whose 4 sides are equal is measure and rectangle is a parallelogram with opposite sides equal.
Since parallelogram, rhombus and rectangle has two pair of parallel sides, therefore, Marcus didn't draw any of these.
We know that trapezoid has only one pair of parallel sides, therefore, Marcus drew a trapezoid.
A(b+c)=ab+ac
a(5+b)=a(5)+a(b)=5a+ab
B is answer
A square has all 4 sides the same.
When given the area of a square , you can find the length of the side by finding the square root of the area:
Side length = √215
Side Length = 14.6628
Rounding to the nearest 0.05 would = 14.65 feet.
4mins---->12 cars
6mins---->(6*12/4)=18
4mins---->12
5mins---->(5*12/4)=15
And so on
3x^2+11x-4=10x-1
3x^2+11x-10x-4+1=0
3x^2+x-3=0
Δ=1^1-4*3*(-3)=1+36=37
x1=(-1+V37)/6
x2=( -1-V37)/6
