Which of the following shows an equivalent form of the equation t²+5t-24=0?

a.(t + 8)(t - 3) = 0
b.(t - 8)(t + 3) = 0
c.(t - 8)(t - 3) = 0

The answer is (a) (t + 8)(t - 3).

Step-by-step explanation:  We are to select the correct equation out of the given  options which is equivalent to the equation t² + 5t -24 = 0.

The first equation is

Since it matches with the given equation, so this option is correct.

The second equation is

Since it does not match with the given equation, so this option is incorrect.

The third equation is

Since it does not match with the given equation, so this option is incorrect.

Thus, the correct option is (a). (t+8)(t-3)=0.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
