Answer:
Just Transposition...
Step-by-step explanation:
12×7=84=d
92-49=43=e
28+57=85=f
96÷16=6=g
11×8=88=h
95+5-29=100-29=71=I
55-6+21=70=j
88+8÷4=96÷4=16=k
19+24-97=-97-43=54=m
-20+17+61=61+3=64=n

Answer:
3x - 20 = 13
Step-by-step explanation:
1. The word is signals the equal sign.
The difference of three times a number and 20 = 13
2. The word difference signals subtraction.
3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.
4. Three times that number = 3x.
The difference = subtraction.
3x-20=13
Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
