solve for n 2n+7=6n-5

n=3

Step-by-step explanation:

you have 2n+7=6n-5

start with subtracting 2n from both sides giving you 7=4n-5

now take the -5 and add 5 to both sides, giving you 12=4n

now divide both sides by 4, now giving you 3=n

the variable has to be on the left every time you finish your work living with n=3

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.
