x² +17x + 72
(x + 9)(x + 8)
x + 9 = 0 ∧ x + 8 = 0
x = -9 ∧ x = -8

4v² - 16v + 7
Break the expression into groups
(4v² - 2v) + (-14v + 7)
Factor out 2v from 4v² - 2v and factor out -7 from -14v + 7
2v (2v - 1) - 7 (2v - 1)
(2v - 1) (2v - 7)
2v - 1 = 0 ∧ 2v - 7 = 0
2v = 1 ∧ 2v = 7

6t² - 54
Factor out the common term 6
6 (t² - 9)
Factor (t² - 9)
6 (t² - 9)
6 (t + 3) (t - 3)
t = -3 * 6 ∨ t = 3 * 6
t = -18 ∨ t = 18

y² - 121
(y - 11) (y + 11)
y = 11 ∧ y = -11
The answer is about 27oz. and this is how you answer it.
<span>pi(d/2)^2 * h = V
3.14(3.6in./2)^2 * 5.9in. =
3.14(1.8in.)^2 * 5.9in. =
3.14 * 3.24 * 5.9in. ~
10.17in. * 5.9in. ~ 60in.^2
and 1in.^2 = 0.45oz. so
60 * 0.45oz. = 27oz.
that is with rounding to the nearest hundredth.

Answer:
y = - 140
Step-by-step explanation:
The statement
y varies jointly as x & z is written as
<h3>y = kxz </h3>
to find y when x = 7 and z = -5 we must first find the relationship between the variables
when y = - 180
z = 15
x = - 3
- 180 = k(15)(-3)
-180 = - 45k
Divide both sides by - 45
k = 4
The formula for the variation is
<h2>y = 4xz</h2>
when
x = 7
z = -5
y = 4(7)(-5)
y = 4(-35)
<h3>y = - 140</h3>
