What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The adult height of a male is about 1.19 times his height at age 12.
The adult height of a female is about 1.07 times her height at age 12.
Now,
Miguel:
Height at the age of 12 = 1.5 m
The height when he is an adult.
= 1.19 x 1.5
= 1.785 m
Ramona:
Height at the age of 12 = 1.6 m
The height when she is an adult.
= 1.07 x 1.6
= 1.712 m
Thus,
The height of Miguel and Ramona as adults are 1.785 m and 1.712 m.

Find the area...
A. 54 sq in
B. 60 sq in
C. 72 sq in
Answer:
60 sq inches
Step-by-step explanation:
Okay, here we are given two different shapes. One being a rectangle, and the other being a triangle. We are trying to find the area of the two shapes combined and in order to do so here are the steps:
The area of a rectangle is as follows:
[tex]b*h=A[/tex]
The area of a triangle is as follows:
[tex]A= \frac{1}{2} b*h\\or \\A=\frac{b*h}{2}[/tex]
Note: Notice how rectancgles have coensideing sides. Meaning that the opposite side of 9in will be 9 in and the opposite side of 6 in will be 6in.
Now lets solve the problem:
[tex]b*h =A\\6*9=54 sq inches\\A=\frac{1}{2} b*h\\A=\frac{1}{2} 6*2\\A=\frac{1}{2}(12)\\A=6 sq inches\\6+54=60 sq inches[/tex]
