Answer:
13
Step-by-step explanation:
Simplify both sides of the equation.
(Combine Like Terms)
Step 2: Add 3 to both sides.
4x−3+3=49+3
4x=52
Step 3: Divide both sides by 4.
Answer:
4x^2 + 12y
Step-by-step explanation:
x + 7y + 4x^2 - x + 5y
4x^2 + 12y
Answer:
12.21
Step-by-step explanation:
2c^2+5c+4
just add numbers with common variables and exponents
Answer:
81x4 = (9x^2)^2, 121a6 = (11a^3)^2, 0.09y12 = (0.3y^6)^2, 4/9b6 = (2/3b^3)^2
Step-by-step explanation:
sqrt of 81 = 9, (we do sqrt because its the inverse to exponents) x^4, x^2 * x^2 = (9x^2)^2
sqrt of 121 = 11, a^6, a^x * a^2 = a^6, x = 3, (11a^3)^2
sqrt of 0.09 = 0.3, y^12 = y^x * y^2, x=6,(0.3y^6)^2
sqrt of 4/9 = 2/3, b^x * b^2 = b^6, x = 3, (2/3b^3)^2
^ = power, * = multiplication
