1. 13. In Diagram 3, the FG is parallel to the line Hl. 3x Find the value of x. G 2x
Based on the information provided, it is not possible to determine the value of x without additional information. The diagram and the statement "FG is parallel to the line Hl" do not provide enough information to solve for x. To find the value of x, we would need to know more about the size of the angles and the lengths of the lines in the diagram.
2. 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}

5. 2. Find the value of 576 byusing prime factorisation.3. Given that the primefactorisation of 21952 is 26 x73, find the value of 21952.
Jawaban:
2. 24
3. 28
Penjelasan dengan langkah-langkah:
2) 576 = 2⁶ × 3²
→ √576 = √(2⁶×3²) = 2³ × 3 = 24
*diakarpangkatkan 2 sama artinya dengan bagi pangkat bil. dalam akar dengan 2
3)³√(2⁶×7³) = 2² × 7 = 28
*diakarpangkatkan 3 sama artinya dengan bagi pangkat bil. dalam akar dengan 3
kesimpulan: suatu bilangan yang diakarpangkatkan n, sama saja dengan membagi pangkat dari faktor-faktor bilangan tersebut dengan n
6. the value of x is...
Jawaban dan Penjelasan dengan langkah-langkah:
sisi alas = 4 cm
sisi miring = 8 cm
tinggi (x) = ???cm
x²= 8² - 4²
x² = 64 - 16
x² = 48
x = [tex]\sqrt{48}[/tex]
x = 4 [tex]\sqrt{3}[/tex]
jadi, x = 4 [tex]\sqrt{3}[/tex]cm

karena bersebrangan maka :
X:180-(30+40+63)
x:180-133
x:47
[tex]\left[\begin{array}{c}KHAZZAMY\\MATH\\BRAINLY\end{array}\right][/tex]
Jawab:47°
Penjelasan dengan langkah-langkah:How to find the value of X:
Eng:
Total degrees of circle: 360°
If we look at the total with the radius under it is half the circle or 180°
And those that are not marked with X are equal to 63°
(because 117° - 180° = 63°)
So.. to find the value of X is:
63° + 30° + 40 = 133°
180° + 133° = 47°
Indo:
Derajat total lingkaran: 360°
Jika kita melihat total dengan juring di bawahnya adalah setengah lingkaran atau 180°
Dan yang tidak bertanda X sama dengan 63° (karena 117° - 180° = 63°)
Jadi .. untuk mencari nilai X adalah:
63° + 30° + 40° = 133°
180° + 133° = 47°
Semoga membantu;)
I hope these helps..
8. prove that the value of (p-x)²+(q-x)²-2(p-x)(q-x) does not depend on the value of x
(p-x)^2 + (q-x)^2 - 2(p-x)(q-x) = [(p-x)-(q-x)]^2
= [p-x-q+x]^2
(p-x)^2 + (q-x)^2 - 2(p-x)(q-x) = [p-q]^2 (proved)
langsung di jabarkan
p°°-x°°+q°°-x°°-2p.2x-2q+2x
= p°°-x+q-2p.4x+2q
p°°-x.4x-2p+2q
=p°°-4x-2p+2q
pindah posisi dimana mana x di depan
-4x+p°°-2p+2q atau 4x-p°°+2p-2q
9. what is the value of x?
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
[tex] \frac{ {2}^{x + 2} + {2}^{x + 4} + {?}^{x + 6} }{128} = \frac{21}{2} [/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = \frac{21}{2} \times 128[/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = 1344[/tex]
[tex](1 + {2}^{2} + {2}^{4} ){2}^{x + 2} = 1344[/tex]
[tex](1 + 4 + 16) {2}^{x + 2} = 1344[/tex]
[tex]21 \times {2}^{ x + 2} = 1344[/tex]
[tex] {2}^{x + 2} = \frac{1344}{21} [/tex]
[tex] {2}^{x + 2} = 64[/tex]
[tex] {2}^{x + 2} = {2}^{6} [/tex]
[tex]x + 2 = 6[/tex]
[tex]x = 6 - 2[/tex]
[tex]x = 4[/tex]
jadi, nilai x adalah 4

16. the quadratic function which takes the value 41 at x=-2 and the value 20 at x=5 and is minimized at x=2 isy=Ax²-Bx+CThe minimum value of this function is D.
the minimum value of that function is -18
17. Find the value of x!
Jawaban:
angle a = 50°
angle b = 70 °
angle c=x
angle a + angle b + angle c = 180°
50°+70°+x=180°
120°+x=180°
x=180°-120°
x=60°
Hence, option (a) is the right answer.
HOPE IT HELPS YOU.....

20. find the value of x
1) 3x + 6x membentuk sudut siku siku maka:
3x + 6x = 90°
9x = 90°
x = 90°/9
x = 10°
2) 2a + 3a + 20 = 180°
5a + 20 = 180°
5a = 180 - 20
5a = 160
a = 160/5
a = 32
3) z = 120°
y = x = 180-120
y = x = 60°
4) 4/6 = 6/a
a = 6×6/4
a = 9 cm
