Hello,
1) k = (-5) * (-5) = 25
3) x = 12 * 0 = 0
5) y = (-4) * (-12) = 48
7) z = 0 * 9 / 1 = 0
9) x= 18 / -3 = -6
11) p = -8 / 8 = -1
13) h = 42 / 14 = 3
15) m = -42 / 6 = -7
17) x = -9 * -11 = 99
19) v = -17 / -17 = 1
21) h = 3,136 / 56 = 0,056
23) x = 4,200 / 30 = 0,14
25) m = 21 * -3 = -63
Bye :)
Subtract 4 from -17, from 3x+4, and from 19:
-21 < 3x < 15
Divide all terms by 3:
-7 < x < 5 (solution)
An area of a circle is calculated by the formula pi(3.14) x radius^2 (squared)
This mean that you would have to type pi x 50^2 (squared) into your calculator which would equal 7853.98. Then round it up to equal 7854cm^2
Answer:
(y + 14)(y - 14)
Step-by-step explanation:
A difference of squares has the general form
a³ - b² and factors as
(a + b)(a - b)
Given
y² - 196
y² = (y)² ⇒ a = y and 196 = 14² ⇒ b = 14
y² - 196
= y² - 14² = (y + 14)(y - 14) ← difference of squares
