Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
<em>The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:</em>
<em></em>
Where L, B and H are the dimensions.
So,
<em>Hence, 1926 cm² of fabrics are needed to cover all surfaces.</em>
The expression which is equivalent to √(-9) is 3i.
<h3>What is Complex number?</h3>
A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.
Here, given expression;
y = √(-9)
y = √9 X √(-1)
y = 3√(-1)
y = 3i
Thus, the expression which is equivalent to √(-9) is 3i.

Answer:
x^3-3x=0
+3x
x^3=3x
ok so that means that that number cubed is the same as a number squared so
x = 0
x = -sqrt(3)
x = sqrt(3)
im going say the answer is mostly likely 0 but it could be the other ones
Hope This Helps!!!
Answer:
The answer is "Grocery sales are lower or no different on Sunday than on other days"
Step-by-step explanation:
Its null hypothesis does not always consider any discrepancy between both the comparable qualities throughout facts and figures. Furthermore, researchers recommend also have lower or even no opposite transactions for Sunday than with other days, because there is no connection between grocery sales and Saturdays and Sundays.
C would be your answer. The original equation is 4(x)^2 - 16. When you shift to the right, you subtract x by that amount. Then you subtract -16 by 3 to go down
