for the following two numbers, find two factors of the first number such that their product is the first number and their sum is
zepelin [54]
You can make some algebraic equations and solve it.
The first would be:
x \times y =  - 21
The second would be
x + y =  - 4
You can then rearrange the second into
x =  - 4 - y
And subsitute it into the first like so:
( - y - 4) \times y = -  21
After that, distribute the y into the parantheses.
{ - y}^{2}  - 4y =  - 21
Subtract the 21 on both sides and multiply by -1 on both sides:
{ - y}^{2}  - 4y  +  21 \\ {y}^{2}  + 4y  -  21
You then can factor it into:
(y + 3) \times (y - 7) = 0
With Zero Product Property, we can determine y to be either -3 and 7. Since the variables are interchangable, you can say the same about x, just that whatever x is, y must be the other value.


Thus, the answer is 7 and -3.

*PLEASE ANSWER DIFFICULT QUESTION* What is the area of the polygon?
LenaWriter [7]

Answer:

Option 4, 64 cm^2

Step-by-step explanation:

The polygon in the shape of a star can be made to be easier to find the area of by cutting it into triangle. For all the "point edges" of the star, we can cut them in half from the vertex to create two right-angled triangles at each edge.

The formula of the area of a triangle is bh/2: the height is given as 6cm, the base is 4cm /2 (after you cut it in half) and so is 2 cm. Since the edges can be cut into two, there are 8 right angled triangles at the edges in total.

To find the area of them:

A=8(bh/2)=8(2*6/2)=48 cm^2

However, we are still missing the part at the centre we haven't found the area of, the square. The area of a square is given by the square of the side length(4cm). Thus, A=4*4=16cm^2

Adding the areas of all the edges and the square:

48 + 16 = 64cm^2

Hence, the area of the polygon is 64cm^2
