A shelf is built on a wall, as shown below. What is the value of x?<br> (2x+1) + (3x-1)

Hoochie [10]

Answer:

x = 18

Step-by-step explanation:

We need to find the value of x.

We know that the sum of angles of a triangle is equal to 180°. So, using this property,

2x+1+3x-1+90 = 180

2x+3x = 180-90

5x = 90

x = 18

So, the value of x is equal to 18.

I need to know the answer

grandymaker [24]

Answer: $f(x)=-(x-5)^{2}(x+2)$

Step-by-step explanation:

There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form $f(x)=a(x-5)^{2}(x+2)$ for some constant a.

To find a, we can substitute the coordinates of the y-intercept, (0, -50).

$-50=a(0-5)^{2}(0+2)\\\\-50=50a\\\\a=-1$

So, $f(x)=-(x-5)^{2}(x+2)$

Answer:

80 mm

Step-by-step explanation:

Pythagorean theorm can be applied here to solve for the length of the last leg, $a^{2}$ + $b^{2}$ = $c^{2}$ , where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:
