Answer:
L = 62.5cm; B = 30cm
Step-by-step explanation:
P = 2 (L+W): L=25cm; W=12cm
=2 (25+12)
=50+24
P = 74cm
For a congruent rectangle with P = 185cm
A: 74 = 2 (25 + 12)
B: 185 = 2( ? + ?)
Since A/B are congruent;
185/75 = 2.5
B = 2 (2.5* (25 + 12)
= 2 ( 62.5 + 30)
= 125 + 60
= 185
Hence, B: L = 62.5cm; B = 30cm
185cm = 2 (62.5 + 30)
Ummm ... idk and ehhem what is the questions in this anyway
Answer:
though this looks difficult. It's easier than you think. Just not visible until its visible. If I knew the answer, i would have told you... sorry.
Answer:
Check the explanation
Step-by-step explanation:
Part A: the sum of Side 1 and Side 2= 5x^2+7x-4
Part B all you have to do is the same thing, but subtract the sum of side 1 and 2 from the total. 5x^3-0x^3=? 4x^2-5x^2=? -x-7x=? -3-4=?
Part C:The closure property states that one polynomial plus another polynomial is also a polynomial. It is the same for addition, subtraction, multiplication, and division
Pretty sure it’s C sorry if wrong
