Answer:
-40
Explanation:
Given
u = 2i - j; v= -5i + 4j and w = j
Required
4u(v-w)
4u = 4(2i) = 8i
v - w = -5i + 4j - j
v - w = -5i + 3j
Substitute
4u(v-w)
= 8i(-5i+3j)
= -40(i*i) [since i*i = 1]
= -40
Hence the required solution is -40
Answer:

Step-by-step explanation:
Answer:
76cm^2
Step-by-step explanation:
Separate the shape into two different rectangles. Then add the area of the rectangles together.
4 x 4 = 16
6 x 10 = 60
16 + 60 = 76
34.I
for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal

35.G
if you divide

so G

36. C

so if you subtract

will equal
