All sides of the squares are congruent. This means that when solving for area:
base x height
the base and height would be the same length, 6.25
Multiply
6.25 x 6.25 = 39.0625
39.0625 ft² should be your answer (if i'm thinking of significant digits correctly)
If it should be a whole number, then 39 ft² is your answer
hope this helps
The <em><u>correct answers</u></em> are:
B- x + y ≤ 10
; and D- x ≥ 4
Explanation:
The illusionist needs at least 4 female volunteers. This means he could use 4 or more; this means x, the number of female volunteers, is greater than or equal to 4:
x ≥ 4
The total of number of volunteers needed is up to 10. This means the illusionist can use 10 or fewer people; this means the total is less than or equal to 10.
The number of female volunteers is x and the number of male volunteers is y; together they create the expression x+y. This gives us
x+y ≤ 10
