Which pair shows equivalent expressions?
Alona [7]

Answer:

Option 3

Step-by-step explanation:

We need to find a pair which shows equivalent expressions.

First equation is

2x+10=-2(x-5)

LHS=2x+10

RHS=-2(x-5)=-2(x)-2(-5)=-2x+10

LHS\neq RHS

Option 1 is incorrect.

Second equation is

-2(x+5)=2x-10

LHS=-2(x+5)=-2(x)-2(5)=-2x-10

RHS=2x-10

LHS\neq RHS

Option 2 is incorrect.

Third equation is

-2x-10=-2(x+5)

LHS=-2x-10

RHS=-2(x+5)=-2(x)-2(5)=-2x-10

LHS=RHS

Option 3 is correct.

Fourth equation is

-2(x–5)=-2X-10​

LHS=-2(x–5)=-2(x)-2(-5)=-2x+10

RHS=-2x-10

LHS\neq RHS

Option 4 is incorrect.

Therefore, the correct option is 3.

Solve the equation for all values of x by completing the square.<br> x^2 + 4x = 32
Black_prince [1.1K]

Answer:

x^2+4x-32=0

(mid-term breaking---4 x 8=32)

x^2+8x-4x-32=0

x(x+8)-4(x+8)

x+8=0 or x-4=0

So x=+4 or x=-8

A cake recipe asked for 4⁄6 of a cup of oil, but Brad accidentally poured 5⁄6 of a cup of oil into the batter. How much extra oi
Blababa [14]
Hello! I would love to help!

Okay, let's first figure out what the problem is asking us. Basically, we need to subtract 4/6 from 5/6 to find the extra left over.

Let's do it!

We need to do 5/6-4/6

To do this, subtract the numerators, or top numbers of each fraction.

The top numbers are 5 and 4
5-4=1

Now, put the new numerator over 6, the common denominator.

1/6

So, your answer is 1/6 cup extra oil.

Hope this helped! Comment if you have questions!
