Answer:
x=2
Step-by-step explanation:
When you sub in these values for the pythagorean theorem you get 1.5^2+x^2=2.5^2
2.25+x^2=6.25
4=x^2
x=2
Answer:
40
Step-by-step explanation:
Answer:
The correct answer is - 242 ft^2
Step-by-step explanation:
Given:
one door : 3*6.5 => 19.5 ft^2
other door: 3*6.5 => 19.5 ft^2
a window: 2*3.5 => 7 ft^2
total = 46 ft^2
area of all four walls: 2h (l+b)
= 2(8) (10+8)
= 16 (18)
= 288 ft^2
paint required excluding doors and window:
=> area of your wall - (area of doors and window)
=> 288 - 46
= 242 ft^2
Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.
<h2>
X + X + 2 + X + 4 = 159</h2><h2 /><h2>
3x + 6 = 159</h2><h2>
-6 -6 ← subtract 6 on both sides</h2><h2 /><h2>
3x = 153</h2><h2>
÷3 ÷3 ← divide both sides by 3</h2><h2 /><h2>
X = 51</h2><h2>
X + 2 = 53</h2><h2>
X + 4 = 55</h2><h2 />
Therefore, the smallest of our three consecutive integers is 51.
