Answer:
Step-by-step explanation:
a² - b² = (a + b)(a - b)
48² + x² = 50²
x² = 50² - 48²
= (50 +48)(50 -48)
= 98 * 2
x² = 196
x = √196

Answer:
1/4 feet
Step-by-step explanation:
since all the strips are 3 feet when they are 12 in number
thus one feet = 12/3= 4 strips
with this knowledge one strip would then be 1/4 feet
if segments OX = OC and perpendicular to those chords, then AB = YZ, the chords are also equal.
Answer:
h(0) = -4
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
h(x) = -3x -4
h(0) = -3·0 -4 = 0 -4
h(0) = -4
_____
<em>Additional comment</em>
In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.
