Using the Pythagorean Theorem, the height of the equilateral triangle is given by:
A. 
inches.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs 
and 
of a right triangle with the length of the hypotenuse h, according to the following equation:
For this problem, we have that:
- The height is one side of the triangle.
- The other side is half the length, of 7 in.
- The hypotenuse is the length, of 14 in.
Hence the height is found as follows:
inches.

16.
17.
Step-by-step explanation:
15.
Using the Identity (a + b)(a - b) = (a² - b²) we get
Consider here a = 5c and b = 3 then we will have
.....as required
16.
Here Factorize 8 such that sum up to be 9
∴ 8 × 1 = 8 and 8 + 1 =9
... as required
17.
Here Factorize 21 such that sum up to be -10
∴ -3 × -7 = + 21 and -3 - 7 = - 10
........as required
Therefore

Answer:
17
Step-by-step explanation:
35 - 18 equals that
-2(4y+6) = 52
-8y -12 = 52
Add 12 on both sides
-8y= 64
Y= -8
Hope this helps!
