Write each expression in factored form.1.2.

-t^2 -t-20

-(t^2+t-20)

-(t+5)(t-4)

  -(t+5)(t-4)

2. 25w^2 +30w+9

  (5w+3) (5w+3)

Answer : (5w+3)^2

the answer is 4.8 units on e2020.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
