Let a, b, c be the lengths of sides of a triangle; a=4.8, b=0.23, and c is a whole number. Find c.

BaLLatris [955]

$\sqrt{4.8 {}^2{ +0.23 {}^{2} } }$
If you solve it, the answer will be

C= 4.80

Seeing as its supposed to be a whole number, you will round up, so it will be 5

Simplify each expression and evaluate it for x=3 1/3, the equation is 3(2x+6)−(3x+1)

Verdich [7]

Value of the expression for x = 3 1/3 is 29.

Step-by-step explanation:

Step 1: Simplify the expression 3(2x+6)−(3x+1)

⇒ 3(2x+6)−(3x+1) = 6x + 18 - 3x + 1 = 3x + 19

Step 2: Find the value of the expression for x=3 1/3

⇒ x = 3 1/3 = 10/3

⇒ 3x + 19 = 3 × 10/3 + 19 = 29

Find the value of X. The diagram is not to scale. Lines F and G are parallel.

sergejj [24]

Step-by-step explanation:

2 × (First Angle + Second Angle) = 360°

5x + 9x + 26 = 360°/2

14x + 26 = 180°

14x = 180 - 26

14x = 154

x = 154/14

x = 11°

The answer is B.
