Answer:

x=65

Step-by-step explanation:

Step 1: Add -3 to both sides.

√x−1+3+−3=11+−3

√x−1=8

Step 2: Solve Square Root.

√x−1=8

x−1=82(Square both sides)

x−1=64

x−1+1=64+1(Add 1 to both sides)

x=65

Which expression is equivalent to 2 (t-4) +1. A 2t-5 B.2t-7 C. 2t-9 D. 2t -3

seraphim [82]

Answer: 2t + -8

Step-by-step explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change this minus to plus a negative.

Now we can distribute or multiply this 2 times

each of the terms inside the set of parentheses.

So we get 2(t) + 2(-4) and this simplifies to 2t + -8.

2t + -8 is the same thing as 2t -8.
