X = Width
2X = Length
2X + 2(2X) = 26 (Perimeter)
6X = 26
X = 4.33333...

Note, the .3333 is repeating, and should be written as .33 with a line over it (can't do it on a keyboard).... It could also be written as 1/3

Need help with this....
Yakvenalex [24]

Answer:

\boxed{\dfrac{f(a+h)-f(a)}{h}=-3a^2-3ah-h^2}

Step-by-step explanation:

f(x)=-x^3+2\\\\\dfrac{f(a+h)-f(a)}{h}\\\\f(a+h)\to\text{substitute x = a + h}\\f(a)\to\text{substitute x = a}\\\\\dfrac{f(a+h)-f(a)}{h}=\dfrac{-(a+h)^3+2-(-a^3+2)}{h}\\\\\text{use}\ (x+y)^3=x^3+3x^2y+3xy^2+y^3\\\\=\dfrac{-(a^3+3a^2h+3ah^2+h^3)+2-(-a^3)-2}{h}\\\\=\dfrac{-a^3-3a^2h-3ah^2-h^3+2+a^3-2}{h}\\\\\text{combine like terms}

=\dfrac{(-a^3+a^3)-3a^2h-3ah^2-h^3+(2-2)}{h}\\\\=\dfrac{-3a^2h-3ah^2-h^3}{h}\\\\=\dfrac{h(-3a^2-3ah-h^2)}{h}\\\\=-3a^2-3ah-h^2

Nady [450]

Answer:

15 and 5 hours.

Step-by-step explanation:

Call x the time taken by the first chap, and y the second.

\left \{ {{x+y = 20 \atop {55x+60y=1125}} \right.

Let's divide by 5 and play with the LHS of the first equation a bit:

11x+ 11y +y = 225\\11(x+y)+y= 225 we know how much x+y is ( first equation!) let's solve.

11(20) +y = 225 \rightarrow y=5 At this point it's easy to check that x=15

Find four consecutive even integers so that the sum of the first three is 2 more than twice the fourth
scoundrel [369]

Answer:

The numbers are : -20,-18,-16,-14

Step-by-step explanation:

Let 1st even integer be =x

So, next consecutive even integer would be =x+2

3rd consecutive even integer would be =x+4

4th consecutive even integer would be =x+6

Sum of first three integers would be =x+x+2+x+4=3x+6

It says sum of the first three is 2 more than twice the fourth,

So we have

3x+6=2+4(x+6)

using distribution to simplify.

3x+6=2+(4\times x)+(4\times6)

3x+6=2+4x+24

3x+6=4x+26

Subtracting 4x from both sides

3x+6-4x=4x+26-4x

-x+6=26

Subtracting 6 from both sides

-x+6-6=26-6

-x=20

∴ x=-20

So first integer =-20

2nd integer  =-20+2=-18

3rd integer =-18+2=-16

4th integer  =-16+2=-14

So, the numbers are : -20,-18,-16,-14
