What is the value of the expression 6n + 45 when n = 7?

value of the equation will be 87

Step-by-step explanation:

by putting value of n as 7 in given equation

we will get,

(6×7) + 45 = 42 + 45 = 87

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
