Answer:
5
Step-by-step explanation:
The cube root of a number is a number that, when multiplied by itself twice, equals the number in the cube root.
So, the cube root of 343 is 7 because 7 * 7 * 7 = 343.
Now the expression looks like: 7 +
The cube root of -8 is -2 because -2 * -2 * -2 = 8
Now the expression is: 7 + (-2)
3/4 * -2 = -6/4, or -1 and 1/2
7 - 1 1/2 = 5 and 1/2

Answer:
The area of the new rectangle is 882 in².
Step-by-step explanation:
Let l be the length and w be the width of the original rectangle,
So, the area of the original rectangle is,
A = l × w ( Area of a rectangle = Length × Width )
Given, A = 72 in²,
⇒ lw = 72 ------- (1),
Since, if the rectangle are changed by a scale factor of 3.5,
⇒ New length = 3.5 l,
And, new width = 3.5 w,
Thus, the area of the new rectangle = 3.5l × 3.5w
( From equation (1) ),
= 882 in²
