PLEASE HELP CORRECT ANSWER WILL GET BRAINLIEST!! Which shows equivalent expressions? a squared + 3 b minus 2 a squared = 3 a squared + 3 b minus 4 a squared a squared + 3 b minus 2 a squared = 3 a squared + 4 b minus 4 a squared Negative a squared + 3 b minus 2 a squared = 3 a squared + 3 b Negative a squared + 3 b + 2 a squared = 3 a squared + 4 b minus 2 a squared (options are down below also)

a^2 + 3b - 2a^2 = 3a^2 +3b -4a^2

Step-by-step explanation:

-a^2 + 3b + 2a^2 = 3a^2 +4b -2a^2

Combine like terms

a^2 +3b  = a^2 +4b

-a^2 + 3b -2a^2 = 3a^2 + 3b

Combine like terms

-3a^2 +3b  = 3a^2 +3b

a^2 + 3b - 2a^2 = 3a^2 +4b -4a^2

Combine like terms

-3a^2 +3b  = -a^2 +4b

a^2 + 3b - 2a^2 = 3a^2 +3b -4a^2

Combine like terms

-a^2 +3b  = -a^2 +3b

The left side is the same as the right

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

infinity is the answer
