Hints:
1) This is an arithmetic sequence.
2) The first member of the sequence is 4.
3) The common difference is 6. To each member, we add 6 to get the next.
4) The formula for the nth term of an arith. sequence is as follows:
l=a + (n-1)d, where l is the LAST term, n is the number of terms, d is the common difference, and a is the first term. Write this out. Play with n, increasing (integer) n until this formula predicts numbers close to 576. Do you get exactly 576 for one of these INTEGER n values? If yes, then 576 is a member of the sequence. If no, then it is not.
Answer:
13 m²
Step-by-step explanation:
To find the area of the shaded region, subtract the sum of the triangles from the area of the shape.
-6/7 = -0.85
-31/50 = -0.62
So -0.62 is greater than -0.85
-0.62 < -0.85
Because the bigger the fraction is the less it actually is and I think the same goes for decimals . Hope I helped
