15(x + 1) + 10(x) = 30(4) - 6( 2x - 1) <em>multiplied by 30 to clear the denominator</em>
15x + 15 + 10x = 120 -12x + 6 <em>distributed</em>
25x + 15 = 126 - 12x <em>added like terms</em>
37x + 15 = 126 <em>added 12x to both sides</em>
37x = 111 <em>subtracted 15 from both sides</em>
x = 3 <em>divided both sides by 37</em>
Answer:
x² + 9x + 20
Step-by-step explanation:
Area of a rectangle can be found by multiplying the base with height (or length with width).
A(r) = l x h.
Multiply. Plug in:
x + 5 for l
x + 4 for h
A(r) = (x +5) * (x + 4)
Use the FOIL method to solve. Multiply the first terms of both parenthesis, the outside terms, the inside terms, and then the last terms. Combine like terms:
A(r) = (x + 5) * (x + 4)
x * x = x²
x * 4 = 4x
5 * x = 5x
4 * 5 = 20
x² + 4x + 5x + 20
x² + (4x + 5x) + 20
x² + 9x + 20
x² + 9x + 20 is your answer.

Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
