Answer:
90.5
Step-by-step explanation:
Diagonal length of the base = √(8²+8²) = 8√2
height = 8,
so area = 8√2 × 8 (since the diagonal and the height makes the rectangle JFHL
so, 8√2 × 8
= 64√2
= 90.5

Answer:
A variable is a letter or symbol, such as a, b, or x, that represents a number. An algebraic expression is a combination of one or more variables; it may include numbers and operation signs. For example, 2 d 5 is an algebraic expression that could represent two times the figure number plus five.

The perimeter of a rectangle = 2(l + w)
l = length
w = width
In this problem,
w = x
l = x + 30
the perimeter = 148
Let's plug our values into the perimeter formula above.
148ft = 2(x + x + 30ft)
Combine like terms.
148ft = 2(2x + 30ft)
Distribute the 2
148ft = 4x + 60
Subtract 60 from both sides
88ft = 4x
Divide both sides by 4
22ft = x
The width = x = 22ft
The length = x + 30 = 22 + 30 = 52ft
Answer:
-5x^5 + 2x^3 - 6x should be your answer
