Answer: 238.95 in²
because this is a regular pentagon
=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.
we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)
=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)
Step-by-step explanation:
Answer:
blue question mark = –
Step-by-step explanation:
6(2x -1) uses the distributive property, which means that both 2x and -1 are multiplied by 6 when expanding the brackets.
6(2x - 1)
= (6 x 2x) + (6 x -1)
= 12x - 6
"evaluate 10(4+3*2)/(2*6-7)
X = 7 for the question in the picture
Set it up as a proportion problem. $2.10 is to x pounds as $3.50 is to 1 pound
=$2.10/x pounds= $3.50/1 pound
Cross multiply
=($2.10 * 1)=($3.50 * x)
=2.10=3.50x
Divide both sides by 3.50
0.6= x
x= 0.6=6/10= 3/5
He can purchase 0.6 (or 3/5 in fraction terms) pounds for $2.10.
Hope this helps! :)
