The formula for perimeter is 2L +2W

Replace w with 20 and L with 11:

2(11) + 2(20) = 22 + 40 = 62

This does not equal 64, so the perimeter cannot be 64 with 20 and 11 being the dimensions.

If x = -3, find<br> pls answer
PolarNik [594]

Answer:

x² - 1 = 8

Step-by-step explanation:

Given the following algebraic expression;

x² - 1

When x = -3

Substituting the value of x, we have;

x² - 1 = (-3)² - 1

x² - 1 = 9 - 1

x² - 1 = 8

Method II.

x² - 1 = (x - 1)(x + 1)

Substituting the value of x, we have;

x² - 1 = (-3 - 1)(-3+ 1)

x² - 1 = -4(-2)

x² - 1 = 8

A design for party favors are in the shape of a regular hexagonal pyramid. The hexagon has a side length of 6 inches. The latera
Nookie1986 [14]

Answer:

Part 1) LA=108\sqrt{2}\ in^2

Part 2) B=54\sqrt{3}\ in^2

Step-by-step explanation:

Part 1) Find the lateral area of the pyramid

we know that

The lateral area of the pyramid, is equal to the area of six congruent isosceles triangles

so

LA=6[\frac{1}{2}(b)(h)]

we have

b=6\ in

Applying Pythagorean Theorem calculate the height of triangle

9^2=(6/2)^2+h^2

h^2=81-9\\h^2=72\\h=\sqrt{72}\ in

simplify

h=6\sqrt{2}\ in

Find the lateral area

LA=6[\frac{1}{2}(6)(6\sqrt{2})]\\\\LA=108\sqrt{2}\ in^2

Part 2) Find the base area

we know that

The area of a regular hexagon is equal to the area of six equilateral triangles

so

Applying the law of sines to calculate the area of triangle

B=6[\frac{1}{2}b^2sin(60^o)]

we have

b=6\ in

sin(60^o)=\frac{\sqrt{3}}{2}

substitute

B=6[\frac{1}{2}6^2(\frac{\sqrt{3}}{2})]

B=54\sqrt{3}\ in^2
