It shouldn't add up to 180 degrees, you're looking for the length of the sides not the degree of the angle. Because it's an equilateral triangle, all sides are the same, so you can just set them equal to each other. D=5

If f(x)=4^x-8 and g(x)=5x+6 find (f+g)(x) ANSWER ASAP PLS

liraira [26]

<h3>Answer: 4^x+5x-2</h3>

Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.

f(x) + g(x) = (4^x-8) + (5x+6)

f(x) + g(x) = 4^x + 5x + (-8+6)

f(x) + g(x) = 4^x + 5x - 2

Firdavs [7]

$\huge\mathcal\pink{Answer}$

radius r = 10 m

volume V = 4188.7902 m3

surface area A = 1256.63706 m2

circumference C = 62.8318531 m

In Terms of Pi π

volume V = 1333.33333 π m3

surface area A = 400 π m2

r-ruslan [8.4K]

Answer:

<em>The polygon area is </em> $51.5 U^{2}$ <em />

Step-by-step explanation:

Points:

(2,7), (8,2), (6,11), (6,5), (11,6)

1. The area of the polygon could be calculate with the eqation:

$A=\frac{1}{2}\left[\begin{array}{ccc}x_{1} &y_{1}\\x_{2} &y_{2}\\x_{3} &y_{3}\\x_{4} &y_{4}\\x_{5} &y_{5}\end{array}\right]$

2. Replace the coordinates in equation for A:

$A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]$

3. Solve the determinant, and calculate A:

$A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]\\A=\frac{1}{2}[(6)(7)+(11)(11)+(8)(6)+(6)(2)]-[(2)(11)+(6)(6)+(11)(2)+(8)(5)]\\A=\frac{1}{2}[42+121+48+12]-[22+36+22+40]\\A=\frac{1}{2}[223]-[120]\\\\A=\frac{1}{2}[103]=51,5 U^{2}$

<em>The polygon area is </em> $51.5 U^{2}$ <em />

Michael has 40 feet of fencing to make a rectangular dog run for his dog, Buddy. One side of the run will be 5 feet long. How lo

AURORKA [14]

P = 2(L + W) ....this is the perimeter of a rectangle
P = 40
L = 5

40 = 2(5 + W)
40 = 10 + 2W
40 - 10 = 2W
30 = 2W
30/2 = W
15 = W <=== ur answer is 15 ft
