Answer:
x = 2.2
Step-by-step explanation:
- 4 (2x + y = 3.4) + (8x + 2y = 11.6)
( - 8x - 4y = - 13.6) + (8x + 2y = 11.6)
- 2y = 2
y = - 1
2x + ( -1 ) = 3.4
2x = 4.4
x = 2.2

Step-by-step explanation:
A rectangular garden has an area of 60 squared feet. The garden is 4 feet longer than it is wide. Which equation can be used to determine the length and width of the garden?
Answer: See explanation
Step-by-step explanation:
Let the width be x
Then, the length will be x+4
Area = Length × Width
Therefore,
x × (x+4) = 60
x² + 4x = 60
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0
x = 6
The width is 6feet
Length = 6+4 = 10 feet

Answer:
-0.76
Step-by-step explanation:
Answer:
-0.76
Step-by-step explanation:
this is pretty simple subtraction but you just take 14.36 and subtract it by 15.12 and you know it will be a negative number because 15.12 is bigger than 14.36 and so your answer is -0.76

Factor the following: 7k^2+3k-10
Step-by-step explanation:
7k² + 3k - 10
= 7k² + ( 10 - 7 ) k - 10
= 7k² + 10k - 7k - 10
= k( 7k + 10 ) - 1( 7k + 10)
= ( 7k + 10) ( k - 1)
Hope it will help :)
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem to determine the roots
k = 1,-10/7
7k^2+3k-10 = 7(k-1)(k+10/7) = (k-1)(7k+10)
-x + y = 4

A right triangle has a leg that measures 15 ft and the hypotenuse measures 24 ft. What would the
length of the missing leg be to the nearest whole number?
Answer:
x=19
Step-by-step explanation:
First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:
[tex]15^{2} +x^{2}=24^{2}[/tex]
Then you square the numbers that you currently have:
[tex]225+x^{2}=576[/tex]
Then subtract 225 from both sides to isolate the x:
[tex]x^{2} =576-225[/tex]
This gives you the equation:
[tex]x^{2} =351[/tex]
Then take the square root of both sides which gives you:
[tex]x=18.7349939952[/tex]
Then round to the nearest whole number which gives you x=19
Please solve all and number them too

The simplification of expression [tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex] is [tex]x^{5}y^{2}[/tex].
SimplificationWhat is simplification?Finding a solution to a complicated calculation that may involve square roots, cube roots, plus and minus integers, division, multiplication, and other mathematical operations is typically referred to as simplification.
What is exponent?The number of times a number has been multiplied by itself is referred to as an exponent.
Rule of exponents:Rule of the product of powers: When multiplying like bases, add the powers together.
Rule of the quotient of powers: When splitting like bases, take the powers out.
Solution for the expression:The expression is given as
[tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]
Applying multiplication and product rule, one power of x will be reduced and 2 power of y will be reduced.
Thus, the the simplified equation will become [tex]x^{5}y^{2}[/tex].
