Answer:
272cm squared
Step-by-step explanation:
figure a, a traingle... to find area formula is
1/2×b×h
1/2×18×17
153
figure b, it's rectangle.so length×width
=7×17
=119
area of the shape=153+119
=272cm squared
Answer:
<h3>C. 800</h3>
Step-by-step explanation:
Given the equation used to calculate the amount of profit, p, made from selling n candy bars expressed as p = 1.50n – 500
To find the number of candies sold for $700, we are going to substitute p = $700 into the given expression and find n as shown;
700 = 1.50n - 500
Add 500 to both sides
700+500 = 1.50n-500+500
1200 = 1.50n
Divide both sides by 1.50
1200/1.50 = 1.50n/1.50
800 = n
Rearrange
n = 800
Hence 800 candy bars must be sold to make $700 profit

Answer: If the dimension of V is n, then V has n elements.
Now, dim(U) + dim(W) = n, this means that the addition of the dimensions of U and W also has n elements.
and because U and W are subspaces of V, you know that every element on U and W is also an element of V.
If U ∩ W = ∅, means that there are no elements in common between U and W.
Because there are no elements in common, then Dim(U) + Dim(W) = dim(U ∪ W) = n
So U ∪ W has the same number of elements as V, and every element of W and U is also an element of V
this means that U ∪ W = V.
