- 10 + SQRT(x + 8) = - 4

Radical Equatiion Entered:

- 10 + SQRT(x + 8) = - 4

Step by step Solution 1:
Isolate the square root on the left hands side.

Original Equation:
- 10 + SQRT(x + 8) = - 4

Isolate: SQRT(x + 8) = 10 - 4

Tidy up:
SQRT (x + 8) = 6

Step 2: Eliminate the radical on the left hand sied:

Raise both sides to the Second Power:

(SQRT X + 8)^2 = (6)^2

After Squaring
X + 8 = 36

Step 3: Solve Linear equation:

Rearrange Equation:
x - 28 = 0

Add 28 to both sides:
x = 28

Possible solution is:

X = 28

Step 4 CHECK:

Original equation, root isolated, after tidy up.

SQRT(x + 8) = 6

Plug in 28 for X
SQRT(28) + 8 = 6

Simplify:
SQRT(36) = 6

Solution Check is
X = 28

Answer:
(A.); X = 28

A rectangle and a square have the same area. The width of the rectangle is 2 in less than the side of the square and the length

lina2011 [118]

The area of a rectangle is A=LW, the area of a square is A=S^2.

W=S-2 and L=2S-3

And we are told that the areas of each figure are the same.

S^2=LW, using L and W found above we have:

S^2=(2S-3)(S-2) perform indicated multiplication on right side

S^2=2S^2-4S-3S+6 combine like terms on right side

S^2=2S^2-7S+6 subtract S^2 from both sides

S^2-7S+6=0 factor:

S^2-S-6S+6=0

S(S-1)-6(S-1)=0

(S-6)(S-1)=0, since W=S-2, and W>0, S>2 so:

S=6 is the only valid value for S. Now we can find the dimensions of the rectangle...

W=S-2 and L=2S-3 given that S=6 in

W=4 in and L=9 in

So the width of the rectangle is 4 inches and the length of the rectangle is 9 inches.

A number sentence is shown below:

d1i1m1o1n [39]

Number sentence is simply a sentence, that uses numbers and arithmetic signs.

The context that can be created from the sentence is: How many bits are there, in $32\frac 14$ bytes
The verbal meaning of $32\frac 14 \div \frac 18 = 258$ is: When $32\frac 14$ is divided by $\frac 18$ , the result is $258$
