A^2 + b^2 = c^2

the sides are 11, 13, and 25

11^2+13^2=290

25^2 = 625

11^2+13^2<25^2

So, this is an obtuse triangle

we know that

The unit rate is $0.65 per foot

To find out the cost, multiply the unit rate by the length of the rope

0.65*(10.8)=$7.02

Using V = ⅓[base area×height]
V= ⅓[ (5.5÷4)² × 2.6]
v= ⅓[ 4.92]
v = 1.6m³

Answer:

$(f+g) (x)=\mid 3x+5\mid+13$

Step-by-step explanation:

<u>Operation of Functions</u>

Given:

$f(x)=\mid 3x+5\mid+6$

$g(x)=7$

The sum of (f+g) (x) is:

$(f+g) (x)=\mid 3x+5\mid+6+7$

We cannot operate with the expression inside the absolute bars, thus:

$\boxed{(f+g) (x)=\mid 3x+5\mid+13}$
