+3 +3
x=14
Answer:
The middle term would be 48x
Step-by-step explanation:
In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.
(3x + 8)^2
(3x + 8)(3x + 8)
9x^2 + 24x + 24x + 64
9x^2 + 48x + 64
Answer:
<h3>Option 2 </h3>
angle 2 = 7x + 1 ( vertically opposite angles)
7x + 1 + 18x + 4 = 180° ( forming linear pair).
7x + 18x + 4 +1 = 180°
25x + 5 = 180°
25x = 180 - 5
25x = 175
x = 7°
angle 2 = 7(7)+ 1
= 50°
Answer to the first triangle: 15To solve this we will use the Pythagorean theorem
Pythagorean theorem formula:

Lets do the first triangle.
17 is the hypotenuse, so its going to replace c in the formula.
8 is the height and it is going to replace a in the formula.
a is what we are trying to find, so our b in the equation is going to be the unknown.





now we know that the missing length in the first triangle (a) is 15Can you solve the Other one?
Just comment if you need help on the other one.
