Answer:
x = 1/2 , x = -1/2
Step-by-step explanation:
Given equation;
169x² - 42.25
Find:
Solution of equation using square root
Computation:
169x² - 42.25
We know that 13² = 169 and 6.5² = 42.25
So,
[13x]² - [6.5]²
a² - b² = (a + b)(a - b)
So,
[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]
So,
13x + 6.5 = 0 , 13x - 6.5 = 0
x = 6.5 / 13 , x = -6.5 / 13
x = 1/2 , x = -1/2
Step-by-step explanation:
<h3>It's
False</h3>
Because (-5+ 1, - 2 + 6) = (- 4, 4) which is not equal to (-4, - 4).
Answer: Try using calculatorsoup dot com, you need to be more specific, and use Find A, C and r | Given d?
radius r = 7.5 in
diameter d = 15 in
circumference C = 47.123889803847 in
area A = 176.71458676443 in2
In Terms of Pi π
circumference C = 15 π in
area A = 56.25 π in2
