I think you meant 'x + 4x = -2'
Combine like terms:
5x = -2
Divide 5 to both sides:
x = -2/5 or -0.4
This statement can be represented as , since the quotient is the answer to a division problem.
Divide.
Multiply.
Simplify. When the numerator and denominator are the same, the fraction is equal to 1.
<h3><u>Answer:</u></h3>
<h3><u>Solution</u><u>:</u></h3>
we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:
Here,
- hypotenuse = 23 feet
- = 76°
- Value of Sin = 0.97
- Perpendicular = ?

The surface area of the rectangular prism is 52 square feet (), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A rectangular prism of
Let, h - height of the rectangular prism
w - Width of the rectangular prism
d - Depth of the rectangular prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,
Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (), if the height is 4 feet, width is 3 feet and depth is 2 feet.
