First square each term to rid of the root sign:
x^2 + 1^2 + 3^2 = 0^2
x^2 + 1 + 9 = 0
x^2 = -10
x = root -10

Solve.<br> 4 x + 6 &lt; − 6<br><br> Thankyou In advance :&gt;
andrew-mc [135]

Answer:

x < -3

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

  • 4x + 6 - 6 < -6 - 6
  • 4x < -12

Step 2: Divide both sides by 4.

  • \frac{4x}{4} < \frac{-12}{4}
  • x < -3

Therefore, the answer is x < -3.

a company uses two vans to transport workers from a free parking lot to the workplace between 7 and 9 a.m. One can has 14 more s
Fiesta28 [93]
Y = x + 14     (the larger bus has 14 more seats)
2x + y = 65       ( 2 x two times the seats , as it makes 2 trips the smaller van so the seats will be full twice maximum)

2x + x + 14 = 65   (sub the value of y = x+14 in the second equation)

3x = 51
x = 17 seat (smaller)
y = 31 seat (larger)

81^3/4 how do i simply/?
Slav-nsk [51]
When you have something to an exponent and the exponent is a fraction it basically means the numerator is the power of the number and denominator is the root of the number.
81^3= 531441
4 root (531441)=27
if you have a graphing or scientific calculator you should be able to enter straight in 81^(3/4).

The shape in the figure is constructed from several identical squares. If the side of each square is 1 unit, what is the area an
Katen [24]

Answer:

Area = 7 square units

Perimeter = 14 units

Step-by-step explanation:

The shape is made up of 7 identical squares and, we are told the side length of each square is 1 unit.

==>Find area of the shape by calculating the area of 1 square, then multiply by the number of square used in the construction.

Thus, area of 1 square = s² = 1² = 1 square units.

Area of shape = 7 × 1 square units = 7 square units

==>Find the Perimeter of the shape by adding all the lengths of the boundary formed by the square to make up the shape.

(Check attachment to understand how we got the measurement of the boundary)

<em>The perimeter = 1 + 1 + 1 + ½ + ½ + 1 + 1 + 1½ + ½ + 1 + 1 + 4 = 14 units</em>
