How do you figure out if it's a dividing fraction word problem or If it's a multiplying fraction word problem

Katena32 [7]

Determined by the signs multiplication is × or using it or could be 2 numbers attached like this 2y but for deciding it's a ÷ or / but that is some of the signs

Answer:

x = -2

TU = 4

UB = 2

Step-by-step explanation:

you can add x^2 with 4x+10 and equate it to 6:

x^2 + 4x + 10 = 6

x^2 + 4x + 4

then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a

so it'll be x = {-4±[√16 - 4(4)]}/2

x= -2

then u can substitute it and find TU and UB

TU= (-2)^2 = 4

UB= 4(-2)+10 = 2

now, with that template in mind, let's take a peek at yours
