Can you please help me!

Step-by-step explanation:

t + 1/t = 2

OK just looking at the equation, if you don't have to show work, if you guess and try t=1 you'll see 1 + 1/1 = 2 works, so t must be 1, and 1^2+1/(1^2) = 2. So the final answer is 2.

If you have to show work, t+1/t=2 is t^2+1=2t, t^2-2t+1=0, solving for t using the quadratic formula, you will get t = 1.

Then you can plug it into t^2 + 1/(t^2) to get 1^2+1/(1^2) = 1+1 = 2.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
