Combine any like terms in the expression. If there are no like terms, rewrite the expression.
10t+9t+6t–10t

15t

Step-by-step explanation:

All the terms have a variable, t, included. Therefore, they are all like terms

10t+9t+6t-10t

10t-10t+9t+6t

10t plus -10t equal 0, therefore they will cancel

9t+6t

15t

it has changed from the width and the height.

step-by-step explanation:

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.
