---------------------------------------
Question 2: 
---------------------------------------
a² + b² = c²
x² + 13² = 15²
x² = 15² - 13²
x² = 56
x = √56
x = 2√14 units

---------------------------------------
Question 4:
---------------------------------------
cos a° = adj/hyp
cos (30) = 12/y
y = 12 ÷ cos(30)
y = 12 ÷ 3√2
y = 4/√2 units

tan a = opp/adj
tan(30) = x/12
x = tan(30) x 12
x = 3√3 x 12
x = 36√3 units

Solve for x<br> 3x + 6 over 3 = 6
Svetradugi [14.3K]

Answer:

X= 4

Step-by-step explanation:

3x+6/3=6

multiply each side by 3 to get rid of the fraction bar

3x+6=6*3

3x +6=18

-6 from both sides

3x= 18-6

3x=12

divide by three on both sides to solve for x

x=12/3

x=4

What are the points for -3x+6y+5=-7
Novay_Z [31]
-3x + 6y + 5 = -7
<u>                -5    -5</u>
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
 6           6
  y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
<u>     +12   +12</u>
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-3(0) + 6y = -12
0 + 6y = -12
<u>+0           +0</u>
      <u>6y</u> = <u>-12</u>
       6       6
        y = -2
  (x, y) = (0, -2)

The prime factorization of 236
mafiozo [28]

Answer:

The prime factors are: 2 x 2 x 59

or Written in exponential form: 2^2 x 59^1

Step-by-step explanation:

236 ÷ 2 = 118 - No remainder! 2 is one of the factors

118 ÷ 2 = 59 - No remainder! 2 is one of the factors

59 ÷ 59 = 1 - No remainder! 59 is one of the factors

together we have the factors 2 x 2 x 59 = 236
