ABCD shows the original location of a shape. FGHI shows the shape reflected across a

Mathematics

AnnyKZ [126]3 years ago

Answer:

A. 5.8

Step-by-step explanation:

if ABCD was reflected to FGHI means that A became F and B became G so AB became (was mapped to ) FG after reflection.

the length ( or distance) after reflection is is preserved ( does not change) so

if AB = 5.8 units then FG =5.8 units.

Determine the surface area

The figure is made up of two cuboids and the surface area of a cuboid is:

Area = 2LB + 2LH + 2BH

Because the bottom part of the upper piece is not visible, the area is calculated as:

Area = 2LB + 2LH + BH

This gives:

Area = 2 * 5*4 + 2 * 4 * 2 + 5 * 2

Area = 66

For the bottom piece:

We calculate its area as Area = 2LB + 2LH + 2BH. However, the area of the invisible part will be subtracted.

So, we have:

Area = 2*3*5 + 2*3*5 + 2*5*5 - 2*5

Area = 100

The total surface area is:

Total = 66 + 100

Total = 166cm^2

Factor trinomial x^2n+10x^n+16​
iragen [17]

Answer:

\large\boxed{x^{2n}+10x^n+16=(x^n+2)(x^n+8)}

Step-by-step explanation:

\text{Use}\ (a^n)^m=a^{nm}.\\\\x^{2n}+10x^n+16=(x^n)^2+10x^n+16=x^n\cdot x^n+2x^n+8x^n+16\\\\=x^n(x^n+2)+8(x^n+2)=(x^n+2)(x^n+8)

A square garden plot measures 180 square feet. A second square garden plot measures 320 square feet. How many more feet of fence
REY [17]

The second garden plot will require 8√5 feet more fence than the first garden plot.

Further explanation:

In order to find the fence, we have to find the perimeter of both squares

So,

Area of Square 1: A1=180 square feet

Area of Square 2: A2=320 Square feet

Let x be the side of square 1:

Then,

A_1=x^2\\180=x^2\\Taking\ square\ root\ on\ both\ sides\\\sqrt{180}=\sqrt{x^2}\\x=\sqrt{2*2*3*3*5}\\x=\sqrt{2^2*3^2*5}\\x=2*3\sqrt{5}\\x=6\sqrt{5}

For second square:

Let y be the side of second square

A_2=y^2\\320=y^2\\Taking\ square\ root\ on\ both\ sides\\\sqrt{320}=\sqrt{y^2}\\y=\sqrt{2*2*2*2*2*2*5}\\y=\sqrt{2^2*2^2*2^2*5}\\y=2*2*2\sqrt{5}\\y=8\sqrt{5}

Perimeter of First Square:

P_1=4x\\=4(6\sqrt{5})\\=24\sqrt{5}\ feet

Perimeter of Second Square:

P_2=4y\\=4(8\sqrt{5})\\=32\sqrt{5}\ feet

The smaller perimeter will be subtracted from larger perimeter to find that how much more fence will be needed.

P_2-P_1=32\sqrt{5}-24\sqrt{5}\\=(32-24)\sqrt{5}\\=8\sqrt{5}\ feet

The second garden plot will require 8√5 feet more fence than the first garden plot.
