Answer:
Please see the attached pictures for the full solution.
length = 3234 m and width = 1614 m
let the width = w then length = 2w + 6
Perimeter = 2 ( length + width )
= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12
given perimeter = 9696 the equating gives
6w + 12 = 9696
subtract 12 from both sides
6w = 9696 - 12 = 9684
divide both sides by 6
w = 
= 1614
width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
Answer:
-3/5
Step-by-step explanation:
the customary way to determine the slope of a linear equation such as this one is to solve the equation for y:
-3x-5y=15 becomes -5y = 15 + 3x after 3x is added to both sides of the original equation.
Solving both sides of this latest result by -5 results in
y = -3 - (3/5)x
The coefficient of x (which here is 3/5) is the slope of this equation.
This strategy works because you would want to make sure that the two numbers add up to the number you subtracted it from. Hope this helped and have an awesome day!
Answer:
The factored form of this is (x - 7)(x -4)
Step-by-step explanation:
In order to factor quadratic equaitons with a 1 as the first coefficient, we look for two numbers that multiply to the last number (28), but add up to the middle number (-11). To do this, we often list the factors of the last number.
Factors of 28
1, 28
-1, -28
2, 14
-2, -14
4, 7
-4, -7
The numbers -4 and -7 satisfy this requirement and are therefore the numbers we want. Now we stick them into parenthesis along with x terms in the front like this:
(x - 7)(x -4)
And that is the fully factored form.
