Answer:
36x² - 9y²
Step-by-step explanation:
We see that the given expression (6x + 3y)(6x - 3y) looks just like the expression (a + b)(a - b). When multiplied out, this is a difference of squares identity that I highly recommend you memorise:
(a + b)(a - b) = a² - b²
Here, a = 6x and b = 3y, so plug these in:
(6x + 3y)(6x - 3y) = (6x)² - (3y)² = 36x² - 9y²
Answer: 45 ft
Step-by-step explanation: 3 times 15 equals 45
<span>A conditional statement has two parts, the hypothesis and
the conclusion. In p and q notation, the hypothesis is always the p and the q
is the conclusion. In a contrapositive statement, the statement would go, “if
not q, then not p”. Therefore, the answer to this item is the second
choice. </span>
Answer:
B
Step-by-step explanation:
The volume (V) of the prism is calculate as
V = lbh ( l is the length, b the width and h the height )
l = h = 4 × 
= 
b = 3 × = 1, thus
V = × 1 × = 
ft³
