Answer:
1 is 9 sq units
2 is 12
3 is 24cm^2
Step-by-step explanation:
2x^2 - 11 = 87
2x^2 = 87 + 11 = 98
x^2 = 98/2 = 49
x = sqrt (49) = + or - 7
Answer:
20,300
Step-by-step explanation:
4/5
Step-by-step explanation:
9x+1=5
or, 9x=5-1
or, 9x=4
therefore x=4/5
D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
