Answer:
Okay so what you are looking at is a triangle with a cross section. That is line segment PQ.You ae asked to find the length of PN. What you are given is the height(s) of NQ (5 units), QM (2 units) and PL (3 units). You can make an educated guess that line NP equals 4 units. Mainly because those two little arrows on lines LM and PQ (that means that the two lines are parallel). hope it helps...
Answer:
the answer is 8x^2+49x+294+1759/x-6
21)
Answer : 2x + 3 (Option D)
When x = 1, 2(1) + 3 = 5
When x = 2, 2(2) + 3 = 7
When x = 3, 2(3) + 3 = 9
When x = 4, 2(4) + 3 = 11
Question 22)
The square of y decreased by the quotient of 28 and 7.
Quotient of 28 and 7 = 28/7
Decreased by square of y = -y²
Therefore the expression is 28/7 - y² (Option A)
147 =20x+47
147 is less than or equal to 20 multiplied by the number of hours she works (x) plus 47 the amount of money she already has
