Answer:
x=-2
Step-by-step explanation:
-12=5(6x+4)+7(x+6)
30x+20+7x+42=-12
37x+62=-12

Answer:

» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides

» On the left hand side, factorise out r

Answer:
2, 10, 50, 250
Step-by-step explanation:
Using the formula with a₁ = 2 , then
a₂ = 5a₁ = 5 × 2 = 10
a₃ = 5a₂ = 5 × 10 = 50
a₄ = 5a₃ = 5 × 50 = 250
The first 4 terms are 2, 10, 50, 250
One interpretation of your intent would be as follows:
16x^11y^8
Find 4 √ [-----------------]. Is that what you meant?
81x^7y^6
4*x^5*√x*y^4
If so, then the correct result would be 4 ---------------------
9*x^3*√x*y^3
and this could be reduced to:
4*x^5 * y^4 * √(x) 4*x^2*y
4 --------------------------- = -------------
9*x^3*y^3 √(x) 9
