drek231 [11]

Answer:

<h2>A = 145 cm</h2><h2 />

Step-by-step explanation:

total length = 445 cm (A + B + C)

A = 45 + B

B = C/2

find A

A + B + C = AC

(45 + B) + (C/2) + C = 445

45 + C/2 + C/2 + C = 445

2C = 445 - 45

C = 400/2

C = 200

B = 200/2

B = 100

A = 45 + 100

A = 145

proof:

445 =  145 + 100 + 200

445 = 445 ----OK

Factor.<br><br> x^2−9x+20<br><br><br><br> Enter your answer in the box.
Zarrin [17]
First, you’d look at what can multiply together to make 20. You can multiply 10x2, 1x20, or 4x5 (or change them so each number is a negative) to make a positive 20. You then must look at which one of these can be added or subtracted together to create -9. Negative 4 and 5 can be subtracted to make -9, so you would factor them out, as well as the x^2, and get the answer (x-4)(x-5).

Answer: (x-4)(x-5)
