<span>the main formula of the lateral area of the rectangular prism is given by Area lateral = perimeter of base x height, in our cas height is 15 inches, length is 5, and width 4. the perimeter of base = (4+5)x2=18, and then the Area lateral =18 x 15 = 270, so the true answer is B=270.</span>
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Amount Noah borrowed from his mother = $17
Amount paid = $8
Change in the amount of money Noah's mother has :
Let initial amount her mother has = x
Hence, the amount she has after Noah paid $8 to her will be :
Initial amount - amount borrowed + amount paid
= x - $17 + $8.
The simplified amount = x - $9
The amount Noah still owes :
Total amount owed - amount paid
$17 - $8 = $9
Here, 1 / (9y - 7) = 2 / 4y
4y = 2(9y - 7)
4y = 18y - 14
18y - 4y = 14
14y = 14
y = 14/14
y = 1
In short, Your Answer would be 1
Hope this helps!
Answer:
<h2>(6 + i)(2 + 9i) = 3 + 56i</h2>
Step-by-step explanation:
Use FOIL: (a + b)(c + d) = ac + ad + bc + bd
and i² = -1
(6 + i)(2 + 9i) = (6)(2) + (6)(9i) + (i)(2) + (i)(9i)
= 12 + 54i + 2i + 9i²
= 12 + 54i + 2i + 9(-1)
= 12 + 54i + 2i - 9 <em>combine like terms</em>
= (12 - 9) + (54i + 2i)
= 3 + 56i
