Step-by-step explanation:
sorry if you dont understand
What is the number line i'm sorry but i can help without a number line that this question is based off of.
Answer:
D. N = w² + 8w + 12
Step-by-step explanation:
The current size is w by w+4, so the area is ...
A = w(w+4)
When each dimension is increased by 2, the new size is (w+2) by (w+4+2). The latter dimension can be simplified to (w+6). Now, the new area is ...
N = (w+2)(w+6) = w² +8w +12 . . . . . . . matches choice D
Answer:
a + b + c = 180º
Step-by-step explanation:
Since the lines are parallel, we can trace a line from angle A to angle C, forming a triangle.
Since the sum of all internal angles of a triangle is 180º, and is this question, the internal angles are a,b and c, we have that a + b + c = 180º
We are assuming A, C and B are on the same line segment AC, of length 17, with B a point in the segment.
|AC|=|AB|+|BC|
17= (4x-9)+(3x+5)
17= (4x+3x)+(-9+5)
17=7x-4
7x=17+4
7x=21
x=21/7=3
Answer: x=3
