Answer:
8x ft^3
Step-by-step explanation:
Step one:
given
dimension of the box
Length= 2ft
width = x ft
Height= 4 ft
Required;
the expression for the volume of the box
Step two:
We know that the volume is expressed generally as
V=L*W*H
V= 2*x*4
V= 8x ft^3
The expression for the volume is V= 8x ft^3
Answer:
x = 25°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
The given triangle is a right triangle which means one of its angle has a measure of 90°
since thd other angle is given as 65 to calculate x we just add the given measures and subtract it from 180
90° + 65 + x = 180
155 + x = 180 subtract 155 from both sides
x = 25°
Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
