Answer:
189 cm²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = × product of diagonals
= × 18 × 21 = 9 × 21 = 189 cm²
12(x-12)=18
x-12=18/12
x-12=3/2
x=3/2+12
x=3/2+24/2
x=27/2
17.01+5+2+3= 27.01 (total expense)
100-27.01= 72.99 (change)
5+2= 7 (total winnings)
72.99+7.00= 79.99 (total change).
F(x) = 1/2 (4)
F(3)is x =3
Evaluate
F(3)=1/2(4) (three on top aka exponet)
F(3)1/2(64)
F(3)=32 so the answer is 32
The sum of the angles in a heptagon is 900°, so we would add the real numbers that we have here:
121°+139°+125°+126°+158°+120°=789°
x would equal the remaining value:
x=900-789
x=111°
