Answer:
-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2) (the last choice).
Step-by-step explanation:
Im ignoring the 2^2 in the equation
The equation transforms to
2x^2 - 3x - 5 = 0 (standard form)
So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)
Answer:
Step-by-step explanation:
E) y +17 =2
y =2-17 = -15
A) 19=a+5
a=19-5= 14
Y) n-6= -50
n=-50+6= -44
L) let the number be p
p+9= -30
p = -30-9= -39
L) -9 + m =20
m = 20+9 = 29
E) 7 = x -23
x = 7+23 = 30
W) 8 +q = -11
q = -11-8 = -19
T) k -8 = -3
k = -3+8 = 5
T) 3 = 10+v
v = 3-10 = -7
H) t-(-1) =45
t+1 =45
t = 45-1 = 44
N) let the number be b
b-20 = -75
b = -75+ 20 = -55
Q) x + (-3) = 22
x = 22+3 = 25
E) p-(-3) =100
p+3=100
p = 100-3 =97
T) 25 + d =8
d = 8-25 = -17
C) -16 + b = 32
b = 32+16 = 48
L) w+38=5
w = 5-38 = -33
O) j+(-61)= -2
j = -2+61 = 59
H) -9 = h+47
h = -9-47 = -56
E) 13=x-13
x = 13+13 = 26
O) t-(-29) = 29
t+29 = 29
t = 29-29 = 0
<h3>Answer: RS = 16</h3>
========================================
Explanation:
The ratio QR : RS : ST is equal to 1 : 4 : 5
This means we have the following three equations
For some positive number x.
Note the ratio QR : RS : ST turns into x : 4x : 5x, which reduces to 1 : 4 : 5 when we divide all three parts by x
.
Along with those three equations, we'll also use QT = 40 as well.
Now turn to the segment addition postulate. Plug in the equations mentioned earlier, and solve for x
.
QT = QR + RS + ST
40 = x+4x+5x
40 = 10x
10x = 40
x = 40/10
x = 4
So we know that
QR = x = 4
RS = 4x = 4*4 = 16
ST = 5x = 5*4 = 20
-----------
As a check,
QR + RS + ST = 4 + 16 + 20 = 40
which is the same as QT = 40
Therefore, we've confirmed that QR + RS + ST = QT is correct and we've confirmed our answers.
