Step-by-step explanation:
Area of shaded =Area of Outer rectangle - Area of Inner rectangle.
Area of inner rectangle = L× B.
L=18
B=11
Area of inner rectangle = 18×11
=198m^2
To find the full breadth of the outer rectangle
=2 in +11 + 2 in
=15
To find the full length of the outer rectangle
=2 in + 18 + 2 in
=22
Area= 22 × 15
Area = 330m^2
Area of shaded portion = 330 - 198
=132m^2
Answer:
2/4 and 4/8
Step-by-step explanation:
Answer:
An expression is one or more terms in an algebraic phrase. An expression does not contain the = sign because it is a phrase. Some examples of algebraic expressions are 2x, 5x + 3, 8m - 5m + 10
Evaluate an Algebraic Expression
To evaluate an algebraic expressiontext annotation indicator for x = 3, means to replace the variable x with the number 3 and then simplify by following order of operations.
Example:
Evaluate the following expression for x = 3.
3 xtext annotation indicator + 5
3(3) + 5text annotation indicator
= 9 + 5
= 14
Write an Algebraic Expression
To write an algebraic expression, look for key words that tell you what operation (add, subtract, multiply, or divide) to use.
Example:
Write an algebraic expression for: The product of x and 5 .
The key word here is product . You may recall that a product is the answer obtained when you multiply. That means we want to multiply x and 5, so we write the expression as 5 x . It should be written the standard way by putting the coefficient in front of the variable.
Step-by-step explanation:
Answer:
no, it is not a proportional relationship.
Step-by-step explanation:
if you divide 315 by 175 you get 1.8
if you multiply 315 by 1.8, you don’t get 420. therefore this is not a proportionally relationship.
hope this helps!
Correct!
Your notes on the right side are correct, too.
<em>In</em>dependent -- <em>not </em>dependent on another variable
Dependent -- dependent on another variable
The height of the plant varies because/due to of the quality/quantity of fertilizer.
So, the height is changed by the fertilizer.
Thus: height is dependent and fertilizer amount is independent.
