Answer: x = 7 or x = -8

x² + x - 56 = 0

⇔ x² + 8x - 7x - 56 = 0

⇔ x(x + 8) - 7(x + 8) = 0

⇔ (x - 7)(x + 8) = 0

⇔ x - 7 = 0

or x + 8 = 0

⇔ x = 7 or x = -8

To find the percentage of a number, first, convert it to a decimal and then multiply.

To convert a percentage to a decimal, move the decimal point over 2 spaces to the left. That makes 80% = 0.80

Then multiply 0.80 by 30.

0.80 • 30 = 24

Peggy got 24 questions correct.

Find the solution of the system of equations. 3x-8y = 19<br>3x + 5y = -46<br>

sattari [20]

(-7,-5)

Step-by-step explanation:

3x-8y = 19

minus

3x + 5y = -46

0x - 13y = 65

- 13y = 65

÷-13

y = - 5

Substitute y = - 5 into one of the functions:

3x-8y = 19

-8 x - 5 = 40

3x + 40 =19

-40

3x. = - 21

÷3

x= - 7

Solution is (-7,-5)

Hope this helps!

VladimirAG [237]

Answer:

8 feet

Step-by-step explanation:

The diagram is attached below.

Note that the values are different but the diagram is similar. In this case,

Hypotenuse =17ft

Adjacent = 15²

Required

Opposite side

To get the feet of landscape edging would be required to outline the edge of the bed, we will use the Pythagoras theorem as shown;

Hyp² = Opp²+Adj²

Opp² = Hyp²-Adj²

l² = 17²-15²

l² = 289-225

l² = 64

l = √64

l = 8feet

Hence the feet of landscape edging would be required to outline the edge of the bed is 8 feet
