The length would be 14.
because 4 less than 3 times the width and the perimeter being 40 you would divide 40 by 2 and you get 20.
4 less than 20 would be 16 but that would make the length equal to the width, therefore, your answer is 14.

Enter number as an integer or decimal.

Answer:

$x$

Step-by-step explanation:

$30-4x>6x-10$

Adding 10 to both sides.

$10+30-4x>6x-10+10$

$40-4x>6x$

Adding $4x$ to both sides.

$4x+40-4x>6x+4x$

$40>10x$

Dividing both sides by 10.

$\frac{40}{10}>\frac{10x}{10}$

$4>x$

∴ $x$

The dDifference in hours between full times and the part timers to work three hours a day is 2 working hours how many hours per

hram777 [196]

full timers work 5 hours a day whereas Part timers work 3 hours a day!

<u>Step-by-step explanation:</u>

Here we have , The difference in hours between full times and the part timers to work three hours a day is 2 working hours . We need to find that how many hours per day to full timers work . Let's find out:

Let full timers work x hours , Part time workers work 3 hours a day , According to question, difference in hours between full times and the part timers to work three hours a day is 2 working hours i.e.

⇒ $x-3 = 2$

Adding 3 to make x term alone :

⇒ $x-3+3 = 2+3$

⇒ $x=5$

Therefore, full timers work 5 hours a day whereas Part timers work 3 hours a day!

One solution to a quadratic function, h, is given.

Margaret [11]

Answer:

B. The other solution to function $h$ is $-4-i\,7$ .

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form $a\cdot x^{2}+b\cdot x + c$ has solutions of the form:

$x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}$ , where both are complex if and only if $\sqrt{b^{2}-4\cdot a \cdot c}< 0$ .

Hence, if one solution of the quadratic function is $-4+i\,7$ , then the other solution is $-4-i\,7$ . The correct answer is B.

Explain how you can find whether 5/6 or 5/8 is greater

ratelena [41]

Because The Smaller The Denominators The Bigger The Fraction Pieces So The Denominators With 6 And 8 The Six Is Smaller So The 5/6 Will be Greater Than 5/8 .

Your current schedule only lets you take two 1-credit courses every six months. You need 12 credits to get the degree you want.

lianna [129]

So,

Since you can only take two one-credit courses every six months, you can earn 2 credits every six months, and 4 credits in one year. Multiplying that by 3, you get 12 credits in 3 years.

It will take 3 years to get the degree.
