4n+5=6n+7 can y’all help me solve this please

-1 = n

Step-by-step explanation:

4n+5=6n+7

Subtract 4n from each side

4n-4n+5=6n-4n+7

5 = 2n +7

Subtract 7 from each side

5-7 = 2n+7-7

-2 = 2n

Divide each side by 2

-2/2 = 2n/2

-1 = n

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.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
