Bu using Pythagoras theorem
(x^2)+(21)^2=(75)^2
Therefore. 5625-441=(x)^2
X^2=5184
Therefore x=72
Third side length=72 units
Distributive property states that z(x + y) = zx + zy.
25(x - y) = 25x - 25y
The answer
the complement of the question is
<span>
Find the interval on the real number line for which the radicand is nonnegative (greater than or equal to zero)</span><span> so that the radical sqrt(8 x - 8) defines a real number. Leave answer in interval notation.
</span>
sqrt(8 x - 8) is definite function if <span>8 x - 8 ≥0, </span>
8 x <span><span> ≥ 8</span> and x </span>≥ 8/ 8 = 1, x <span>≥ 1, so the interval solution is [1, infinity[</span>

Answer:
in the ordered pair; ( x = 27/4 , y = 1/4 )
Step-by-step explanation:
Given that:
The system of the equation shown below is:
-2x - 14y = 10
2x + 2y = 14
We are to use the elimination method to determine the ordered pair.
From the above equation:
-2x - 14y = 10 --- (1)
2x + 2y = 14 --- (2)
Add both equation 1 and 2 together in order to eliminate x, then we can solve for y first.
-2x - 14y = 10
<u> 2x + 2y = 14 </u>
<u> 0 - 16y = -4 </u>
<u />
- 16 y = - 4
divide both sides by - 16, Then:
-16y /-16 = -4/-16
y = 1/4
Since y = 1/4, Then from equation (2), x will be :
2x + 2y = 14
2x + 2(1/4) = 14
2x + 1/2 = 14
2x = 14 - 1/2
2x = 13.5
x = 13.5/2
x = 27/4
Thus, in the ordered pair; ( x = 27/4 , y = 1/4 )
