Answer:
The value of (x + y)³ is 1728.
Step-by-step explanation:
First, you have to find the value of x + y :
x² + 2xy + y² = 144
x² + xy + xy + y² = 144
x(x + y) + y(x + y) = 144
(x + y)(x + y) = 144
(x + y)² = 144
x + y = √144
x + y = 12
Next, the value of (x + y)³ :
(x + y) = 12³ = 1728
Answer:
below
Step-by-step explanation:
Where’s the picture. Please show it
<span>First step is find total height of all the figures expressed in feet:
Liem: 6 ft 2 inch = 6,167 ft
Eli: 5 ft 9 inch = 5,75 ft
Faith 6 ft
Simon: 5 ft 4 inch = 5,34 ft
To calculate the total height we need to know that 12 inches are 1 foot
6’2”+5’9”+6+5’4”= 22 ft 15 inch = 23 ft 3 inch
Another way is by adding decimal figurel:
6,167 + 5,75 + 6 + 5,34 = 23,25 feet
Then we know that 3 feet are 1 yard, so then total height is:
23,25 / 3 = 7,75 yards</span>
Answer:
RS = 10
Step-by-step explanation:
We are told that to get ∆QRS, the scale factor of ⅖ was used. To get side RS, we would multiply the side length of the side that corresponds to RS.
YZ corresponds to RS.
YZ = 25
Thus,
RS = 25*⅖
RS = 10
