Answer:

7\sqrt{3} or 12.12

Step-by-step explanation:

The pythagorean theorem states that <em>a</em>^2 + <em>b</em>^2 = <em>c</em>^2, with<em> a</em> and <em>b</em> representing the legs and <em>c</em> representing the hypotenuse.

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = 7\sqrt{3} or 12.12

Answer:

x = sqrt(147)

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.

x^2 +7^2 = 14^2

x^2 +49 = 196

Subtract 49 from each side

x^2 = 147

Take the square root of each side

sqrt(x^2) = sqrt(147)

x = sqrt(147)

Solve x^2 + 2x - 48 = 0
Georgia [21]

Answer:

x = - 8, x = 6

Step-by-step explanation:

{x}^{2}  + 2x - 48 = 0 \\  \\  {x}^{2}  + 8x - 6x - 48 = 0 \\  \\ x(x + 8) - 6(x + 8) = 0 \\  \\ (x + 8)(x - 6) = 0 \\  \\ x + 8 = 0 \:  \: or \:  \: x - 6 = 0 \\  \\ x =  - 8, \:  \:  \:  \: x = 6 \\

Make a table of values for f(x) = 18x2 + 10x + 1.
serg [7]

Answer/step-by-step explanation:

To make a table of values, substitute each value of x into the given equation function f(x) = 18x^2 + 10x + 1

For x = -3,

f(-3) = 18(-3)^2 + 10(-3) + 1

f(-3) = 18(9) + (-30) + 1

f(-3) = 162 - 30 + 1 = 133

For x = -2,

f(-2) = 18(-2)^2 + 10(-2) + 1

f(-2) = 18(4) + (-20) + 1

f(-2) = 72 - 20 + 1 = 53

For x = -1,

f(-1) = 18(-1)^2 + 10(-1) + 1

f(-1) = 18(1) + (-10) + 1

f(-1) = 18 - 10 + 1 = 9

For x = 0,

f(0) = 18(0)^2 + 10(0) + 1

f(0) = 18(0) + 0 + 1

f(0) = 0 - 0 + 1 = 1

For x = 1,

f(1) = 18(1)^2 + 10(1) + 1

f(1) = 18(1) + 10 + 1

f(1) = 18 + 10 + 1 = 29

For x = 2,

f(2) = 18(2)^2 + 10(2) + 1

f(2) = 18(4) + 20 + 1

f(2) = 72 + 20 + 1 = 93

For x = 3,

f(3) = 18(3)^2 + 10(3) + 1

f(3) = 18(9) + 30 + 1

f(3) = 162 + 30 + 1 = 193
