Answer:

Step-by-step explanation:

Area of Square = (x+5)²= x² + 10x + 25

Area of rectangle = 2x  * x  = 2x²

area of rectangle + 1 = Area of square

 2x² + 1 = x² + 10x +25

2x² + 1 - x² - 10x - 25 = 0

x²  - 10x - 24 = 0

(x - 12) (x + 2) = 0

x - 12 = 0   ;   Ignore x + 2  because length wont come in negative

x = 12

Answer:

No real solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x^2+x+5=2x+1

Step 2: Subtract 2x+1 from both sides.

2x^2+x+5−(2x+1)=2x+1−(2x+1)

2x^2−x+4=0

Step 3: Use quadratic formula with a=2, b=-1, c=4.

x= −b±√b2−4ac/2a

x= −(−1)±√(−1)^2−4(2)(4)/2(2)

x= 1±√−31/4

5mn^4 • 5m^2 n^3<br><br>Does that even makes sense <br><br>​
xeze [42]

Answer:

25m^3n^7

Step-by-step explanation:

Let's write out the equation

5mn^4 • 5m^2n^3

When we multiply exponents with similar bases, you add them together.

For example 2^2 • 2^2= 2^4

Numbers with no exponent are to the power of one

For example: 2= 2^1

Now that we know this, let's combine like terms

5 • 5=25

m^1•m^2=m^3

n^4•n^3=n^7

Answer: 25m^3n^7

Vsevolod [243]

Answer:

Total dollars = 35 dollars.

Step-by-step explanation:

Below is the given values:

Number of cups = 8 cups

Number of gallons = 3 gallons

Price of soil per quart = $2.50

Now convert the cups and gallons into quart.

Total quart = 8 cups + 3 gallons

Total quart = 8 / 4 quart + 3 x 4 quarts

Total quart = 2 quart + 12 quart

Total quart = 14 quart

Total dollars amount = $2.50 per quart x 14 quart

Total dollars = 35 dollars.

What is the solution to the equation 3 x+ 2 = -x-57<br> X=-8<br> o x=-7<br> o x=7<br> O X=8
luda_lava [24]

Answer:

x = -59/4

Step-by-step explanation:

3 x+ 2 = -x-57

Add x to each side

3 x+x+ 2 = -x+x-57

4x+2 = -57

Subtract 2 from each side

4x +2-2 = -57-2

4x = -59

Divide each side by 4

4x/4 = -59/4

x = -59/4
