Angle 3 and 4 are supplementary angles and create a straight line.
This means when added together they need to equal 180 degrees.
Angle 3 = 180 - angle 4
Angle 3 = 180-40 = 140 degrees.
Answer:
The mode is 4 and the median is 8
Step-by-step explanation:
The mode is the number the occurs the most in the set, and as you can see 4 appears twice. The median is the number that lies in the middle of the set when put together from least to greatest. When you write it out it results in 2,4,4,8,9,10,12. As you can see the number 8 lies right in the middle, with three numbers on it's left and three numbers on it's right. Hope this helps :)

Answer:
-4
Step-by-step explanation:
The dot product is the sum of products of corresponding coefficients.
u·v = (4)(-1) +(0)(2) = -4
u·v = -4
Answer:
the perimeter is 28 and the area is 49
Step-by-step explanation:
a square has equals sides and i counted seven on each side for the perimeter. you multiply seven by seven to find the area
Answer:
(D)
Step-by-step explanation:
If it has a leading coefficient of 1, then it can not (A) or (B) because they have a two in front of it. Next, we can check the roots -2 and 7. -2 goes with (x+2), while 7 goes with (x-7). Therefore, you can already see that the answer is (D). To make sure. let us check the root 5 with multiplicity of 2. 5 goes with (x-5), implying that there must be 2 (x-5)'s. Only (D) satifies that as well, so the answer must be (D).
