Answer: a) 17767 b) 32860 c) 13860
Step-by-step explanation:
a) 91+491(12)(3)=17767
b) 31000(1.06)=32860
c) 32860-19000=13860
Let the two numbers be x and y, then
x + y = 62 . . . . . . . (1)
x - y = 18 . . . . . . . .(2)
subtracting (2) from (1), we have:
2y = 44
y = 22
From (2), x + 22 = 62
x = 62 - 22 = 40
therefore, the two numbers are 40 and 22.
Find 2 numbers that multiply to 6 and add to 5.
3*2 = 6
3+2 = 5
x^2 + 5x+6 = (x+3)(x+2) = 0
Set each factor equal to zero.
x+3 = 0 ----> x = -3
x+2 = 0 -----> x = -2
Answer:
There are two zeros at -2 and -3.
Answer:
Step-by-step explanation:
Given:
AP = 3,
PQ = 5,
QB = 7,
CP = 2,
QD = 14
Required:
1. PD
2. EQ
SOLUTION:
1. Based on Intersecting Chords Theorem,
AP = 3
PB = PQ + QB = 5 + 7 = 12
CP = 2
PD = ?
Plug in the values into the equation
Divide both sides by 2
b. Based on Intersecting Chords Theorem,
EQ = ?
QD = 14
AQ = AP + PQ = 3 + 5 = 8
QB = 7
Plug in the values into the equation
Divide both sides by 14
