Answer:
99.96 square feet
Step-by-step explanation:
The formula for the area of a rhombus is (pq)/2, where p and q represent the two diagonals:
A=pq/2
=(16.8)(11.9)/2
=199.92/2
=99.96 square feet
B as if you plug the co-ordinates into the equation and it equals 10: (3x4)-2= 12-2 =10
A doesn't work as the answer is 20
C doesn't work as the answer is 14
D doesn't work as the answer is -20
Answer:
f(-12)=-18
Step-by-step explanation:
since we are replacing the x for -12 that means we will have the equation f(-12)=1/2(-12)-12 which would give us f(-12)=-6-12 which would equal -18 so the answer for f(-12) is -18
