<span>A = (9x2 + 60x + 100)  = (3x + 10)^2 or = (3x + 10)(3x + 10) ft^2

so the side length = </span>(3x + 10) feet

<span>when x = 7 feet.

P = 4 * </span>(3x + 10)
P = 12x + 40
P = 12(7) + 40
P = 84 + 40
P = 124 feet

The expressions that are equal to 61 are

  • |−61|
  • The distance from zero to −61
  • −(−61)
  • The opposite of −61

<h3>How to determine the expressions?</h3>

The value of the expression is given as:

Value = 61

Next, we evaluate the options:

<u>Option 1: |−61| </u>

The expression is given as:

Expression = |-61|

Remove the absolute sign

Expression = 61

Hence, |-61| equals 61

<u>Option 2: The distance from zero to −61 </u>

This is represented as:

Distance = |-61 - 0|

Evaluate the difference

Distance = |-61|

Remove the absolute sign

Distance = 61

Hence, the distance from zero to −61 is 61

<u>Option 3: The opposite of 61 </u>

The opposite of 61 is represented as:

Opposite = -(61)

Evaluate

Opposite = -61

Hence, the opposite of 61 is -61

<u>Option 4:−(−61) </u>

The expression is given as:

Expression = -(-61)

Remove the bracket

Expression = 61

Hence, -(-61) equals 61

<u>Option 5: the opposite of −61</u>

The opposite of -61 is represented as:

Opposite = -(-61)

Evaluate

Opposite = 61

Hence, the opposite of -61 is 61

<u>Option 6: −|−61| </u>

The expression is given as:

Expression = -|-61|

Remove the absolute sign

Expression = -61

Hence, -|-61| equals -61

<u>Option 6: −|61| </u>

The expression is given as:

Expression = -|61|

Remove the absolute sign

Expression = -61

Hence, -|61| equals -61

Find the perimeter of the polygon. Round your answer to the nearest tenth.
lakkis [162]

Answer:

Option B.

Step-by-step explanation:

From the given figure it clear that the the vertices of the polynomial are Q(2,0), R(4,5), S(8,7), T(6,4) and U(10,3).

Distance formula:

d=\sqrt{(x-2-x_1)^2+(y_2-y_1)^2}

Using distance formula, we get

QR=\sqrt{\left(4-2\right)^2+\left(5-0\right)^2}=\sqrt{29}

RS=\sqrt{\left(8-4\right)^2+\left(7-5\right)^2}=2\sqrt{5}

ST=\sqrt{\left(6-8\right)^2+\left(4-7\right)^2}=\sqrt{13}

TU=\sqrt{\left(10-6\right)^2+\left(3-4\right)^2}=\sqrt{17}

QU=\sqrt{\left(10-2\right)^2+\left(3-0\right)^2}=\sqrt{73}

Now, the perimeter of the polynomial is

Perimeter=QR+RS+ST+TU+QU

Perimeter=\sqrt{29}+2\sqrt{5}+\sqrt{13}+\sqrt{17}+\sqrt{73}

Perimeter=26.12996

Perimeter\approx 26.1 units.

Therefore, the correct option is B.

Helpppppppppppp plzzzzzzzzzzzzzzzzzz!
prisoha [69]

Answer: F=140

Step-by-step explanation:

720=(x-60)+(x-40)+(x-20)+130+120+110

720-130-120-110=3x-120

360=3x-120

360+120=3x

480=3x

480/3=x

160=x

F=160-20

Next problem

102+31+x=180

133+x=180

x=180-133

x=47
