Answer:

x = -12

Step-by-step explanation:

5x - 2(4x+11) = 14

5x - 2*4x -2*11 = 14

5x - 8x - 22 = 14

-3x = 14 + 22

-3x = 36

x = 36/-3

x = -12

Check:

5*-12 -2(4*-12 + 11) = 14

-60 -2(-48+11) = 14

-60 -2(-37) = 14

-60 + 74 = 14

A right triangle has legs of 5 ft and 6 ft. What is the length of the hypotenuse? _____ ft. A. 7.8 B. 3.3 C. 11.0 D. 1.0
Delicious77 [7]

Answer:

<h2>7.8</h2>

Option A is the correct option.

Step-by-step explanation:

Base (b) = 5 ft

Perpendicular (P) = 6 ft

Hypotenuse (h) = ?

Now,

Using Pythagoras theorem,

{h}^{2}  =  {p}^{2}  +  {b}^{2}

{h}^{2}  =  {(6)}^{2}  +  {(5)}^{2}

{h}^{2}  = 36 + 25

{h}^{2}  = 61

h =  \sqrt{61}

h = 7.8 \: ft

Hope this helps...

Good luck on your assignment

Which of the following statements is not true about the numbers 7 and -7? They are opposite numbers. They form a zero pair. They
Irina-Kira [14]

We need to find which statement is not true:

Let us check each statement:

-They are opposite numbers.

Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.

-They form a zero pair:

7-7 =0, the statement is true.

- They have the same absolute value

The absolute value is the not negative value no matter the sign.

Hence, l7l= 7 and l-7l= 7.

-They have a sum of -14.

Then:

7+(-7) = 0

Therefore, the last statement "They have a sum of -14" is not true.
