I think ur right because it’s -2 and positive n and it starts at negative 2 and has n as a positive. I'm not good at math but hope we are right lol.

Fran is putting up a tent. Each triangular end of the tent has sides of length 6 ft. What is the approximate height of the tent,

Klio2033 [76]

Answer:

height = 5 ft

Step-by-step explanation:

The height will divide the base of the triangle in two parts of 3 ft, making two smaller right triangles.

Then, to find the height, we can use the Pythagoras' theorem in one of these triangles:

6^2 = 3^2 + height^2

36 = 9 - height^2

height^2 = 27

height = 5.19 ft

Rounding to the nearest foot, we have height = 5 ft

Write an equation and solve: Your math homework has 6 more than three

lorasvet [3.4K]

Answer: 33 math problems.

Step-by-step explanation:

Let x = Number of math problems

y= Number of history problems

According to the question , we have

$3y+6=x\ \ \ \ \ (i)\\\\ x+y=42\ \ \ \ (ii)$

We can rewrite (i) as $x-3y=6$ (iii)

Now, subtract (iii) from (ii), we get

$y-(-3y)=42-6\\\\\Rightarrow\ y+3y=36\\\\\Rightarrow\ 4y=36\\\\\Rightarrow\ y= \dfrac{36}{4}\\\\\Rightarrow\ y=9$

Put this in (i), we get

$x=3(9)+6 = 27+6=33$

Hence, you have to complete 33 math problems.

The length of a rectangle is 7 meters more than four times its width if the area of the rectangle is 650 square meters, find the

mrs_skeptik [129]

Let the width be x.
Width = x
Length = 4x + 7

The area is 650 m²

x(4x + 7) = 650
4x² + 7x - 650 = 0

Using quadratic formula:
$x = \dfrac{-b \pm \sqrt{b^2 - 4ac} }{2a}$

a = 4, b = 7, c = -650

$x = \dfrac{-7 \pm \sqrt{7^2 - 4(4)(-650} }{2(4)}$

$x = 11.9 \ or\ x = -13.7 \text {(rejected, length cannot be negative)}$

Width = 11.9m
Length = 4(11.9) + 7 = 54.6m

Answer: Length = 54.6m and width = 11.9m
