Answer:
9 a^2 + 30 a + 25 the anwser is A
Step-by-step explanation:
Expand the following:
(3 a + 5)^2
(3 a + 5) (3 a + 5) = (3 a) (3 a) + (3 a) (5) + (5) (3 a) + (5) (5) = 9 a^2 + 15 a + 15 a + 25 = 9 a^2 + 30 a + 25:
Answer: 9 a^2 + 30 a + 25
Today is March, 19th 2016
so from 1992 have been: 2016 - 1992 = 24 years
but the date is from October 30th, so we are not at 24 years just yet, we are at 23 years and the months and days since last 30th October, that is:
November + December + January + February = 4 months
and some days more, 19 days because today is 19th, so the total is:
23 years, 4 months, 19 days
Answer:
m∠KHL = 43°
Step-by-step explanation:
From the picture attached,
m∠KHL ≅ m∠GHL [Given in the picture]
Now substituting the values of the angles,
(3x + 1) = (5x - 27)
1 + 27 = 5x - 3x
28 = 2x
14 = x
m∠KHL = (3x + 1)° = (3 × 14) + 1
= 42 + 1
= 43°
Therefore, measure of ∠KHL = 43°
So you would act like it was an equal sign and solve it like normal. Subtract 45 from both sides. Get 14"="2x. Divide by 2 and get 7 >x. If you were to multiply or divide by a negative than you would flip the sign, but you leave it in this case because you divided by a positive. I hope that helps.
