Answer:

88 m^2

Step-by-step explanation:

They're simply trying to confuse you with the rest of the numbers.

7+4 = 11

^To get the base length.

8 is the height.

11*8=88.

88m^2 is the answer. Multiply each of the three parts seperately (the middle rectangle and the two triangles on either side of it) Area of a rectangle is the base multiplied by height. the base is 7 and the height is 8 (7*8=56). Area of a triangle is half of the base multiplied by the height. The base is 4, half of the base would be 2 and the height is 8 (2*8=16). There are two of those triangles so multiply 16 by 2 to get 32. 56+32=88.

Why does the expression i to the power 4n+2 is always equal to -1

Alexandra [31]

Answer:

See Below.

Step-by-step explanation:

We are given:

$i^{4n+2}$

Using exponent properties:

$=i^{4n}\cdot i^2$

Rewriting:

$=(i^4)^n\cdot i^2$

Since i⁴ = 1 and i² = -1:

$=(1)^n\cdot -1$

1 to any power is still 1:

$=1\cdot -1 = -1$

Please help me no one would help me i really need help due tomorrow.

Option B is correct.

Step-by-step explanation:

A triangle has vertices A(-3,-1), B(-6,-5), C(-1,-4). We need to find the transformation that will produce the triangle with vertices: A(3,-1), B(6,-5), C(1,-4)

Seeing the vertices of transformed triangle, we observe that the x-coordinate of vertices has been opposite of that in the original vertices, while y-coordinate remains same.

This shows it is reflection over y-axis. In which x-coordinate becomes the negative (opposite) of original coordinate while y-coordinate remains the same.

So, Option B is correct.

4x+2y=10 <br> X-y=13 <br> Write in (x,y)

Bad White [126]

Answer:

(x = 6, y = -7)

Step-by-step explanation:

Solve the following system:

{4 x + 2 y = 10 | (equation 1)

x - y = 13 | (equation 2)

Subtract 1/4 × (equation 1) from equation 2:

{4 x + 2 y = 10 | (equation 1)

0 x - (3 y)/2 = 21/2 | (equation 2)

Divide equation 1 by 2:

{2 x + y = 5 | (equation 1)

0 x - (3 y)/2 = 21/2 | (equation 2)

Multiply equation 2 by 2/3:

{2 x + y = 5 | (equation 1)

0 x - y = 7 | (equation 2)

Multiply equation 2 by -1:

{2 x + y = 5 | (equation 1)

0 x+y = -7 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 12 | (equation 1)

0 x+y = -7 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 6 | (equation 1)

0 x+y = -7 | (equation 2)

Collect results:

Answer: {x = 6 , y = -7
