Answer:
a = 28 / √2
Step-by-step explanation:
Isosceles triangle therefor a = b
use pythagorean theorem
a² + a² = c²
2a² = 28²
a² = 28² / 2
Take the square root of both sides
a = 28 / √2
Answer:
<h2>x = 8</h2>
Step-by-step explanation:
x³ - 3x² + 2x - 336 = 0
Find one factor of the polynomial
That's
x - 8
because when its value is equated to zero substituted into the polynomial will give you zero
Factorize x - 8 out
We have
(x - 8) ( x² + 5x + 42) = 0
x - 8 = 0
x = 8
x² + 5x + 42 = 0
Since the roots of this quadratic equation are complex and are not real numbers
<h3>x = 8</h3>
Hope this helps you
Answer:
That’s correct
Step-by-step explanation:
y < 4 does mean that y is less than 4. if it helps. Wherever the open side is, means that one is greater. I always look at it like an alligator eating the bigger number
