6 X 899 solve the sum by distributive property
1. 6 X 899 solve the sum by distributive property
Jawaban:
The form of the product of 6 × 37 using the distributive property is
= 6 × (30 + 7)
= (6 × 30) + (6 × 7)
= 180 + 42
= 222
Discussion
Using Distributive Properties in Multiplication
There are many quick and easy ways to solve a math problem, including:
1) Commutative (exchange)
What is meant by commutative is to change or reverse the position of a number. Commutative only applies to addition and multiplication because in the process of multiplication and addition, even though the place is exchanged or reversed, the result remains the same.
So, a × b is the same as b × a. Likewise a + b the result is the same as b + a.
2) Associative (grouping)
What is meant by associative is to group the counting process.
(a × b) × c = a x (b × c)
(a + b) + c = a + (b + c)
Just like commutative, associative also only applies to multiplication and addition.
3) Distributive (spread)
What is meant by distributive is to describe the form of multiplication into the form of addition or subtraction.
a × (b + c) = (a × b) + (a × c)
Well, on this occasion we will discuss problems related to the distributive property of multiplication.
Is known :
Multiply 6 × 37
Asked:
Solve with the distributive propertySolution:
First, the tens and ones in the number 37 are converted to addition form.
6 × (30 + 7)
Next, the tens and ones are multiplied by 6.
(6×30) + (6×7)
Then look for the results of the multiplication and the results are added up
= 180 + 42
=
= 6 × (30 + 7)
= (6 × 30) + (6 × 7)
= 180 + 42
= 222

7. 4) Which of the following represents all the possible values of x that satisfy the equation below? X X x − 3 2x 2 *
Nilai x memenuhi persamaan yaitu x = 0 atau x = 4. Soal ini berkaitan dengan materi mencari nilai x dari suatu persamaan.
Penjelasan dengan langkah-langkahDiketahui :
Koreksi soal, mungkin maksud Anda persamaan x/(x-3) = 2x/2
Ditanyakan :
Solusi dari permasalahan tersebut
Jawab :
Langkah 1
x / (x - 3) = 2x / 2
Jika dipindah ruas akan menjadi :
x . 2 = 2x . (x – 3)
Selanjutnya kita lakukan operasi
2x = [tex]2x^{2}[/tex] – 6x
0 = [tex]2x^{2}[/tex] – 8x
0 = 2x (x – 4)
x = 0 atau x = 4
Jadi, x yang memenuhi adalah x = 0 atau x = 4

8. find the equation of the straight line which passes through the point (-2,4) and is parallel to the line y=2x +5.
y = 2x + 5
m = 2
y - b = m(x - a)
y - 4 = 2(x -(-2))
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 4 + 4
y = 2x + 8

11. find the equation of the circle whose radius is 5 which touches the circle x² + y² - 2x -4x -20 = 0
Penjelasan dengan langkah-langkah:
x² + y² - 2x -4y -20 = 0
cari titik pusatnya dulu
x = –(–2)/2 = 1
y = –(–4)/2 = 2
jadi pusatnya (1, 2)
dengan r=5
kita cari titik potongnya
dengan :
(a+1)/2 = 5
a + 1 = 2(5)
a = 10-1
a = 9
(b+2)/2 = 5
b+2 = 2(5)
b = 10-2
b = 8
Persamaannya menjadi :
(x - a)² + (y - b)² = r²
(x - 9)² + (y - 8)² = 5²
x² - 18x + y² - 16y + (-9)² + (-8)² - 5² = 0
x² + y² - 18x - 16y + 81 + 64 - 25 = 0
x² + y² - 18x - 16y + 120 = 012. The line equation which is trough point (-3,7) and having gradient -2 is
(y-y1) = m (x-x1)
(y-7) = -2 (x-(-3))
y-7 = -2 (x+3)
y-7 = -2x -6
y+2x = -6 +7
y+2x = 1 atau -2x-y = -1

14. Find the value of m which the equation x^2+ (m – 3)x + 4 = 0 has two real roots.
• Persamaan Kuadrat
-
Nilai m agar x² + (m - 3)x + 4 = 0 memiliki 2 akar - akar real adalah m ≤ -1 atau m ≥ 7
• Pembahasan •
D ≥ 0 → Memiliki dua akar - akar reaL
x² + (m - 3)x + 4 = 0
a = 1
b = m - 3
c = 4
0 ≤ b² - 4ac
0 ≤ (m - 3)² - 4(1)(4)
0 ≤ m² - 6m + 9 - 16
0 ≤ m² - 6m - 7
0 ≤ (m + 1)(m - 7)
HP = { m ≤ -1 atau m ≥ 7 }
•••
-AL
Jawab:
m ≥ 7 atau m ≤ - 1
Penjelasan dengan langkah-langkah:
akan memiliki akar akar bilangan real jika D ≥ 0
bentuk umum persamaan kuadrat adalah ax² + bx + c = 0, maka dari soal diperoleh
a = 1
b = m - 3
c = 4
karena D ≥ 0, maka
D ≥ 0
b² - 4ac ≥ 0
(m-3)² - 4.1.4 ≥ 0
m² - 6m + 9 - 16 ≥ 0
m² - 6m - 7 ≥ 0
(m - 7)(m + 1) ≥ 0
maka didapat m ≥ 7 atau m ≤ -1
jadi, HP = {m | m ≥ 7 atau m ≤ - 1}
