Answer: C
Step-by-step explanation:
Answer:
The correct answer is 6 cm.
Step-by-step explanation:
The measure of all angles of the triangle is given to be 60 degrees. This invariably means we are talking about an equilateral triangle as all angles of an equilateral triangle are equal.
Also all sides of an equilateral triangle is known to be equal. Therefore the measure of all sides of the concerned triangle are equal.
Given the measure of two length of sides are 6 cm respectively.
Therefore the length of side 3 is 6 cm, equal to the other two sides.
Check the picture below.
let's recall that the midsegment of a triangle is the segment that's half-way to both endsides and is at the same time parallel to the 3rd side, is also half the length of the parallel side, so-called the base.
so, for example, we know L, M and N are midpoints to each segment, that means that LM is a midsegment and parallel to PR and also half the length of PR, same is true for LN and MN.
Answer:
A) 360 adults
Step-by-step explanation:
c=quantity of child
a=quantity of adult
9c+12.5a=5220
a+c=440 then c=440-a
substitute for c
9(440-a)+12.5a=5220
3960-9a+12.5a=5220
reduce
3.5a=1260
a=360
Answer:
1. C. Yes, because a sum of cubes can be factored
2a. false
2b. false
2c. true
2d. false (based on what is written in the equation; refer to step-by-step)
Step-by-step explanation:
1. Both 3 and 8 can be cubed, which is why x^3+8 can be factored (x+2)(x^2-2x+4)
2a. a^2-b^2 can be factored by the perfect square rule, so it should be (a-b)^2
2b. both terms are perfect squares, so you can factor, making it (a+b)(a-b)
2c. You can factor using the perfect square rule, making it (a+b)^2
2d. Most of what is in the equation is true, yet the correct solution would be (a-b)(a^2+ab+b^2)
