Calculate the area of the figure below using the following information:

vekshin1

Answer:

106.5 square units.

Step-by-step explanation:

See the attached diagram.

The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.

So, Area of Pentagon ABCDE = Area of Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.

⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)

What is the factored form of x^12y^18+1

Black_prince [1.1K]

Answer: The required factored form of the given expression is

$(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

Step-by-step explanation: We are given to find the factored form of the following algebraic expression:

$E=x^{12}y^{18}+1.$

We will be using the following formula:

$a^3+b^3=(a+b)(a^2+ab+b^2).$

Now, we have

$E\\\\=x^{12}y^{18}+1\\\\=(x^4y^6)^3+1^3\\\\=(x^4y^6+1)\{(x^4y^6)^2-x^4y^6\times1+1^2\}\\\\=(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

Thus, the required factored form of the given expression is

$(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

AleksAgata [21]

Answer:

1. -6=7(p-2)-8(8+2p)

P = -8

2. -8n-5=-8(n-2)

The sides are not equal there for there is no solution

39. Find the value of the expression if x= -1 and y= 6.

Nadya [2.5K]

Answer:

The answer is B

Step-by-step explanation:

$x = - 1 \: and \: y = 6 \: solve \: \frac{xy}{2} \\ \frac{ - 1 \times 6}{2} = \frac{ - 6}{2} = - 3 \\$
