Answer:

Square pizza

Step-by-step explanation:

d = Diameter of round pizza = 16 inches

a = Side length of square = 15 inches

More crust means the edge length of the pizza is greater. Edge length is given by the perimeter.

Circumference or perimeter of the round pizza

$C=\pi d\\\Rightarrow C=\pi\times 16\\\Rightarrow C=50.27\ \text{inches}$

Perimeter of the square is

$P=4a\\\Rightarrow P=4\times 15\\\Rightarrow P=60\ \text{inches}$

So, the square pizza has more crust compared to the round pizza.

A book is opened to a page at random. The product of the facing page numbers is 9312. What is the sum of the facing page numbers

timofeeve [1]

Answer:

193

Step-by-step explanation:

Let's "cheat" a little on this one

We know that the numbers are consecutive

so lets take the square root of 9312 to get close

√9312 = 96.4987046545

Consecutive numbers around 96.4987046545

96 * 97 = 9312

96 + 97 = 193

-------------------------------

The "correct" method would be to set up an equation

x(x + 1) = 9312

x² + x = 9312

x² + x - 9312 = 0

Then use the quadratic equation to solve for x

Which you can do if you're so inclined.

Me, I'm happy to have "cheated"

How to solve this inequality -8×+18>-22

Ksju [112]

Answer:

x < 5

Step-by-step explanation:

Step 1: Solve for x

-8x + 18 > -22

-8x + 18 - 18 > -22 - 18

-8x / -8 > -40 / -8

When dividing by negative, it flips the sign

x < 5

Full steps and all reasons, thanks!

You can focus on the two sub-triangles ABC and ACD

We know that they are both right triangles, because we're given that AC and BD are perpendicular.

The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:

$AD^2 = AC^2+CD^2$

$AB^2 = AC^2+BC^2$

But since we're given $BC=CD$ , the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
