X + 12 = 30
Reorder the terms:
12 + X = 30
Solving
12 + X = 30
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + X = 30 + -12
Combine like terms: 12 + -12 = 0
0 + X = 30 + -12
X = 30 + -12
Combine like terms: 30 + -12 = 18
X = 18
Simplifying
X = 18</span>

Step-by-step explanation:
Perimeter of rectangle = all sides added
= 3+3+7+7 =20
volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257
area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15
volume of pyramid = base height x base width x height / 3
= 300
side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5

Answer:
m∠A = 65°
Step-by-step explanation:
<em>Opposite angles of the quadrilateral add up to 180</em>.
This means x + 148 = 180 -> <em>x = 32</em>.
m∠A = 2x + 1 -> 2(32) + 1
m∠A = 65°.
