Answer:

-14 > -16

Step-by-step explanation:

> = greater than

< = less than

To help you know which is less than what in negative numbers use a number line.

In negative numbers what would usually be bigger than the other number is smaller in negatives. like 69 is bigger than 34 but im negatives -69 would be smaller than -34.

Answer:

$A=150.72$ $m^2$

Step-by-step explanation:

Using the formula for the surface area of a cylinder

$A=2\pi rh+2\pi r^2$

As we know that r=3, h=5, and $\pi$ =3.14 we can substitute in these values into the equation and then solve it

$A=2(3.14)(3)(5)+2(3.14)(3)^2\\\\A=94.20+56.52\\\\A=150.72$

Select the two values of x that are roots of this equation.<br>x + 2x - 6 = 0

VLD [36.1K]

For this case we must solve the following quadratic equation:

$x ^ 2 + 2x-6 = 0$

Where:

$a = 1\\b = 2\\c = -6$

The solution is given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting:

$x = \frac {-2 \pm \sqrt {2 ^ 2-4 (1) (- 6)}} {2 (1)}\\x = \frac {-2 \pm \sqrt {4 + 24}} {2}\\x = \frac {-2 \pm \sqrt {28}} {2}\\x = \frac {-2 \pm \sqrt {2 ^ 2 * 7}} {2}\\x = \frac {-2 \pm2 \sqrt {7}} {2}\\x = -1 \pm \sqrt {7}$

Thus, we have two roots:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$

ANswer:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$

The length of a photograph of Mr. Lemley playing golf is 1475 inches. If the area

Mice21 [21]

Answer:

1.12 × 10^-3

Step-by-step explanation:

The computation of the width of the photograph is as follows:

As we know that

Area of the rectangle = length × width

33 ÷ 20 square inches = 1475 inches × width

So, the width is

= Length ÷ area

= 1475 inches ÷ (33 ÷ 20 square inches)

= 1.12 × 10^-3
