Answer:
48 cm²
Step-by-step explanation:
The copper part is two equal triangles, find a triangle's area by counting squares and multiply by two.
Total copper=(Triangle area)(2)
=b(h)(½)(2)
=b(h)
=(6)(8)
=48 cm²
So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.
Answer:
-4/7 is the smallest. then it's -1/19 and then finally it's 7/4
The answer is probably the opposite which in this case would be -19 ?
The answer should be -3xy^2 (4x^2y^3 + 3x - 4y)
