Answer:
(x+4)(x-4)
Step-by-step explanation:
x^2-16 = x^2 +4x - 4x +16
So Factorization is: (x+4)(x-4)

For question 4,
units,
For question 5,
units.
Step-by-step explanation:
Step 1:
Since the given polygons are similar to each other, all the ratios of one polygon to the other will remain equal for all the values of the two similar polygons.
We take the ratio of the same sides of both polygons i.e. the ratio of the lengths or the ratio of the widths.
Step 2:
For question 4, the first rectangle has a length of 9 units while the width is 3 units.
For the second rectangle, the length is x as x is greater than the width in the first rectangle. The width is 6 units.
The ratio of the first rectangle to the second is;
So
units.
Step 3:
The shapes in question 5 are made of a square and a triangle.
For the first shape, the side length is 6 units while the side of the triangle is 10 units.
For the second shape, the side length is 5 units while the side of the triangle is x units.
The ratio of the first shape to the second is;
So
units.
The sum of all positive integers that satisfy the condition as described is; 100
The number set of n is therefore;
n = {1, 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}.
According to the question;
- If n is odd, then n is a multiple of 5.
The data set therefore includes all odd numbers; This is so because the question says; if n is odd; then n is a multiple of 5.
The sum of all positive integers that satisfy the condition is therefore;
- 1 + 3 +5 +7 + 9 +11 +13 +15 +17 +19 = <em>100.</em>

The first step is finding the height of the cake. The formula for the volume of a box: Volume= length x width x height. So given the volume and length and width: 100= 9 x 11 x h. 100=99h and solve for h. h= 1.01 inches so the batter is more than one inch thick. That means that the matter needs to be baked at 350 degrees Fahrenheit. The formula to convert from Fahrenheit to Celsius: T(C)= (T(F)-32) x (5/9). So (350-32) x (5/9) = 176.667. Rounded to the nearest whole number is 177 degrees celsius.
Answer:
9
Step-by-step explanation:
What you're going to do is
-take the area and divide it by the amount of sides (a square has 4)
36/4=9
