Answer:
R, T, S
Step-by-step explanation:
R+S+T=180 degrees
9x-2+4x+36+5x+20=180
18+54x=180
54x=162
x=3
R=9*3-2 (substitute x with 3)
R=25
S=4*3+36
S=48
T=5*3+20
T=35
Shortest to longest: R, T, S
Answer:
C) 2 × 3 × 5
Step-by-step explanation:
Volume of a cuboid = lbh = 30 cm³
A) 1 × 1 × 5 = 5 cm³ ≠ 30 cm³
B) 5 × 10 × 15 = 750 cm³ ≠ 30 cm³
C) 2 × 3 × 5 = 30 cm³ ✔
D) 1 × 2.5 × 4 = 10 cm³ ≠ 30 cm³
=》The correct option is C) 2 × 3 × 5 as it makes 30 cm³, which is the required volume.

Answer:
iii. (l + m - n)(l - m + n)
vi. (5a -b) ( 5b - a)
Step-by-step explanation:
iii. l² - (m - n)²
= (l + m - n)(l - m + n)
vi. 4(a+b)² - 9(a-b)²
= (2(a+b))² - (3(a-b))²
= (2(a+b) + 3(a-b)) (2(a+b) - 3(a-b))
= (2a+2b + 3a - 3b) (2a+2b - 3a + 3b)
= (5a -b) ( 5b - a)
