How can we tell if a number is divisible by 4

Answers

Answer 1

Answer: if a number ends in a two digit number that is divisible by 4 then the who number is divisible by 4.

eg: 608, 728

because 08 is divisble by 4 then so is 608 and the same for 28 and 728

Answer 2

Answer:

The last two digits of the number are divisible by 4.

Which diagram represents the factors of m2 – 10m + 16 ?

Answers

Answer:

Last Table

Step-by-step explanation:

We are given a equation

m²-10m+16

We have to find which diagram represents the factor of m²-10m+16

we will use splitting the middle term method:

m²-10m+16 can also be written as

m²-8m-2m+16

= m(m-8)-2(m-8)

=(m-2)(m-8)

so, Last Table represents the factors of m²-10m+16

The last table is the correct choice. Because when you use the X method on the equation your answers from that is (m-8)(m-2).

How can I find the missing values to complete the table? I am a bit confused.

Answers

To find the missing values, find the slope of the equations. Since both equations are linear, we know that the slope is linear. We can find the slope of the equations by using the equation for slope.

Slope for Y1:
m = (y2 - y1) / (x2 - x1) = (11 - 15) / (-3 - -5) = -4 / 2 = -2

Therefore, for Y1, you can subtract 2 from each previous answer to fill in the column. So underneath 15 would be 13, then 11, then 9, etc.

Slope for Y2:
m = (y2 - y1) / (x2 - x1) = (-12 - -15)) / (-4 - -5) = 3 / 1 = 3

Therefore, for Y2, you can add 3 from each previous answer to fill in the column. So underneath -15 would be -12, then -9, then -6, etc.

The areas of two similar polygons are in the ratio 64:81. find the ratio of the corresponding sides.

Answers

If the areas of two similar polygons are in the ration 64:81, then the ratio of their corresponding sides are $(8)/(9)$

What are polygons?

"A polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross."

The simple polygons are triangles (3 sides), quadrilaterals (4 sides), and pentagons (5 sides).

Now if we take the given polygon as square (4 sides).

Then,

Let the sides of squares are a and b.

$(a^(2) )/(b^(2) )=(64)/(81) \n(a)/(b)=\sqrt{(64)/(81) } \n(a)/(b)=(8)/(9)$

Hence, the ratio of the corresponding sides of polygon is $(8)/(9)$

Answer is 8:9. The easiest example is a square. If the polygons are squares with areas of 64 and 81 then the sides of the squares are 8 and 9. Therefore, the ratio of the corresponding sides is 8:9

What two numbers add to negative 9 but multiply to 24

Answers

There aren't any numbers that add to 24 but multiply to 9. But you can still factorise - remember, you only need to get numbers that add up to the middle number if the coefficient of y^2 is 1. That means if you just have y^2, not 2y^2 or 3y^2 or 16y^2 like we do here.

16y^2+24y+9 = (4y+3)^2
