Step-by-step explanation:

4a⁴: 2² × a⁴

5a²: 5 × a²

Lcm: 2² × 5 × a⁴

4×5×a⁴

20a⁴

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

you never say the total so we cant find the percentage used for petrol
