Answer:
Step-by-step explanation:
∠EMC = ∠EMD + ∠DMC
∠EMC = 90
∠EMD + ∠DMC = 90
∠EMD + 20 =90
∠EMD = 90 - 20
∠EMD = 70
∠FMD + ∠DMB = 180 {Linear pair}
90 + ∠DMB = 180
∠DMB = 180 - 90
∠DMB = 90
We will start by expanding (or multiplying through) with 3(n+4)
We get:
3n + 12
3n can be expanded to equal 2n+n, so the correct answer will be
2n + 12 + n
Simply add the options together and see what one matches 3n + 12
2n + 12 + n = 3n + 12, which in turn equals 3(n+4)
ANSWER: 2n + 12 + n
