Answer:
Part a-
area= 35
perimeter= 31
part b-
area= 25
perimeter= 18
Step-by-step explanation:
to find the area of a triangle you multiply 1/2Bh
so for part A:
A= 
(10)(7) (honestly, you can just input the whole equation into the calculator)
A=(5)(7)
A= 35
and for part B:
A= (8.34)(6)
A= (4.17)(6)
A=25.02 (or just 25)
THEN, to find the perimeter you add up all of the sides
so for part A:
P= 14 + 10 + 7 = 31
and for part B:
P= 4 
+ 8 + 5 = 17 
or 18
I hope this helps :)
I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12

Answer is $17.60 Rate of pay
Step by step.
First we know she worked the following hours
8:45 - 12:15 = 3.5 hours
13:15 - 17:30 = 4.25 hours
Total hours worked per day 7.75 hours
She works 5 days x 7.75 hours = 38.75 hours per week
She makes $682 for 38.75 hours worked
Divide pay by hours worked to find rate of pay
$682 / 38.75 = $17.60 per hour rate of pay
Due to "order of operations" rules, you MUST do the multiplication -5(12x+8) first, eliminating the parentheses long the way:
8 - 60x - 40
Now combine the 8 and -40 and rewrite the entire answer in 2 (not 3) terms.
