Factor 1/8 out of 1/8x-49/8​
svetoff [14.1K]

Answer:

1/8(x - 49)

Step-by-step explanation:

When we factor out something, we are basically finding common factors from multiple terms to take out. Example:

ab + ac; factored out: a(b + c)

If we want to factor out 1/8 from 1/8x - 49/8, we simply divide the two terms by 1/8.

\frac{1/8}{1/8x} The 1/8 cancel out giving us x so:

1/8(x - __)

The next term,

\frac{49/8}{1/8}

When two fractions divide, you flip the bottom one and multiply them both,

\frac{49}{8} *\frac{8}{1}

giving us 49.

The answer is: 1/8(x - 49)

6 16x + 5y = -2<br> 4x - y=-2
Grace [21]

Answer:

x=2/9,y=26/9

Step-by-step explanation:

This is a simultaneous equation

16x+5y=-2..(1)

4x-y=-2...(2)

From (2) make y the subject of formula

y=4x+2..(3)

Substitute (3) into (1)

16x+5(4x+2)=-2

16x+20x+10=-2

36x-10=-2

Add 10 to both sides

36x=8

Divide both sides by 36

x=8/36

Divide both denominator and numerator by 4

x=2/9

Substitute the value x into (3)

y=4(2/9)+2

y=8/9+2

Let the LCM be 9

y=8+18/9

y=26/9

Therefore x=2/9,y=26/9

Rewrite the expressions below by completing the square<br> 2 + 4+ 1
Lady bird [3.3K]
STEP BY STEP EXPLANATION
(Mark brainliest pls)

Square root is 2 square + 4 square + 1 because 1 does not enable a square perhaps for negatives to be imputed, and we know 2 square will be 1 hence,

1 x 1 = 1 squared
2 x 2 = 4 squared
Perhaps for 1, you will have to use a formula equation and add tang maybe. Etc I don’t know if tang but u will also have to convert 1 to a decimal to find the square root of 1, 1 is an odd number so it will end up with remainder decimals or just do 1x1, etc.


Hence u

(2 square + 4 square) + 1square?

It depends on addition or order of operations subtraction addition or you will might use multiply
if the subject is about multiply or Division so try and do it because i don’t know if I’m right

..

REMEMBER

PEMDAS

Please Excuse My Dear Aunt Sally

Subtraction

ORDER OF OPERATIONS.


try and solve it hope this helps!

The area of a square concrete slab is 20 square feet. Find the side length of the square concrete slab if the area is increase b
guapka [62]

The side length of the square concrete slab if the area is increased by 25% is 5feet

The formula for calculating the area of a square is expressed as:

A =  L² where:

L is the side length of the square

Given the area of the square concrete slab = 20 square feet

20 = L²

L =√20

If the area is increased  by 25%, new area will be:

An = 20 + (0.25*20)

An = 20 + 5

An = 25 sq.ft

Get the new length

An = Ln²

25 =   Ln²

Ln = √25

Ln = 5feet

Hence the side length of the square concrete slab if the area is increased by 25% is 5feet
