Answer:
Width = 15 ft
Step-by-step explanation:
Given formula,
→ A = L × W
Let us assume that,
→ Length = 4x
→ Width = x
→ Area = 900 ft²
Then the value of width will be,
→ A = L × W
→ 900 = 4x × x
→ 4x² = 900
→ x² = 900/4
→ x = √225
→ [ x = 15 ft ]
Hence, the value of width is 15 ft.
Jaqleen unloads a truck in x hours and Marco takes 2x hours.
Working together (x*2x) / (x+2x) = 5 hours
2x^2 / 3x = 5 Multiplying both sides by 3x equals 2x^2 -15x = 0
x = 7.5 hours
So Jaqleen takes 7.5 hours and Marco takes 15 hours
Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals
5 hours Correct!!
Answer:
Domain of a geometric or arithmetic sequence is the counting numbers unless otherwise noted.
The expression is simplified to give -7x^2 - 11x
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions that contains variables, constants, factors and coefficients.
They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.
From the information given, we have;
(- x^2 - 5x ) - ( 6x^2 + 5x)
expand the bracket
-x^2 - 5x - 6x^2 - 5x
collect like terms
-7x^2 - 11x
Thus, the expression is simplified to give -7x^2 - 11x
