X=-198(substitute the value of x into the equation)
x-6y=90
-198-6y=90(solve the equation)
y=-48(a possible solution is)
(x,y)=(198,-48). (check yhe solution)
-198-12= 210(simplify)
-198-6(-48)=90
-210=-210( the ordered pair is a solution)
90=90
(x,y)=(198,-48)
is the answer
Try A:
6^(2*1.87) = 813.365
Try B:
6^(2*1.61) = 320.366
Try C:
6^(2*3.73) = 638275.725
Try D:
6^(2*1.13) = 57.362
Which one seems like the best answer?
You just subtract the number
Answer:
390cm
Step-by-step explanation:
1. find area of rectangle
1. 15cm x 20cm= 300 cm
2. find area of triangle
1. 1/2 (12 x 15)= 90cm
300+90
