Susan is investment her money so she can have more money in her pocket
#1: 4(x + 3)
We just have to distribute the 4 throughout the rest of the problem. So, (4 times x) + (4 times 3) = 4x + 12
#2: -7(4 - y)
This is the same concept, but with a negative sign at the front. So, (-7 times 4) - (-7 times y) = -28 + 7y

b
Step-by-step explanation:
fairly certain it is b
The area of a rhombus is computed as follows:
A = p*q*1/2
where p and q are the diagonals of the rhombus.
In this case:
A = AC*BD*1/2
A = 6*4*1/2
A = 12 square inches
Answer:
65
Step-by-step explanation:
(4-7i)(4+7i) =16 + 28i-28i -49i^2 ➡16 - 49i^2
16 + 49 = 65
the fault here is i^2= -1 and -1 multiplied by -49 is +49 not -49
