Answer: The answer is D (4). The expression cannot be factored.
Answer:
Step-by-step explanation:
so first what you want to do is split the shape in to
Draw a line down where the 2 is.
you should have a rectangle and a triangle
then you find the area of the rectangle
Rectangle:
5 x 2 = 10m^2
After than you try to find the triangles area
the bottom of the triangle is 9m but since to split it in 2 you will now have 7m
multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2
Add your two areas together and you will get 27.5m^2
Answer:
QT and ST
RS and SW
Step-by-step explanation:
There are 2 of the answer choice that are correct. QT and ST, RS and SW.
Those lines do intersect each other at a corner of the cube.
Answer: -1/2
Step-by-step explanation:
Use double-angle identities:
cos(2θ)=cos^2θ−sin2^θ
cos(2θ)=1−2sin^2θ
cos(2θ)=2cos^2θ−1
sin(x)=1/2
cos(2x)=1−2sin^2x=1−2(1/4)=1/2
cos(4x)=2cos2^(2x)−1=2(1/4)−1=-1/2
