Answer:

Step-by-step explanation:

lol this is a weird math question

Hydrogen bonds occur only when hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. Anything else isn't considered a hydrogen bond.

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x

marusya05 [52]

we have

$x^{2} + 27x + 162$

Using a graph tool------> to resolve the second order equation

the solution is

$x=-18\\ x=-9$

$x^{2} + 27x + 162=(x+18)*(x+9)$

therefore

the answer is the option

length = (x + 18) inches and width = (x + 9) inches

Please assist me with these problems using the 45-45-90 relationship triangles

TiliK225 [7]

Answer:

see below

Step-by-step explanation:

side opposite 90 angle = x $\sqrt{2}$

sides opposite 45 angle = x

the multiplication and division by $\sqrt{2}$ should be self explanatory

1. x = 5, y = 5

2. v = 10, u = 10

3. x = $\sqrt{10}$ , y = $\sqrt{5}$

4. m = 5, n = $\frac{5\sqrt{2} }{2}$

5. a = $\frac{3\sqrt{2} }{2}$ , b = $\frac{3\sqrt{2} }{2}$

6. a = $\frac{3\sqrt{2} }{2}$ , b = $\frac{3\sqrt{2} }{2}$

Write the equation (in point-slope form) for the line parallel to y = x + 4 and passes

Tanya [424]

Answer:

$y = x-7$

Step-by-step explanation:

Step 1: Write the equation in point-slope form

Point Slope Form: $y-y_{1}=m\left(x-x_{1}\right)$

Plug in the numbers and solve

$y - (-2) = 1(x - 5)$

$y + 2 = x - 5$

$y + 2 - 2 = x - 5 - 2$

$y = x-7$

Answer: $y = x-7$
