The dimensions of a rectangle are given in

alexandr1967 [171]

Option A and Option F

The expressions that represent the perimeter of rectangle are 4s + 1 and $2(2s + \frac{1}{2})$

Solution:

From figure,

Length = s

Width = $s + \frac{1}{2}$

The perimeter of rectangle is given as:

perimeter = 2(length + width)

Substituting the values we get,

$perimeter = 2(s + s + \frac{1}{2})\\\\perimeter = 2(2s + \frac{1}{2})$

Thus option F is correct

On further simplification,

$perimeter = 2(2s + \frac{1}{2})\\\\perimeter = 4s + 2(\frac{1}{2})\\\\perimeter = 4s + 1$

Thus Option A is correct

What is the discriminant of the quadratic equation 0 = –x2 + 4x – 2?

kifflom [539]

Recall that the discriminant is b² - 4ac
So, substitute, b = 4, a = -1 and c = -2

Δ = 16 - 4(-1)(-2) = 16 - 8 = 8
