Answer:
See below in bold.
Step-by-step explanation:
1. x/8 = 15/24
Cross multiplying:
24x = 8*15
x = (8*15)/24
x = 5.
2. 5/6 = 35/x
5x = 6*35
5x = 210
x = 210/5
x = 42.
3.<em> </em>18/42
Divide top and bottom by 6:
18 / 6 / 42/6
= 3/7.
4. 15/75
Divide top and bottom by 15:
= 1/5.
Answer:
since, v=a(square) ×h
Step-by-step explanation:
v=a(squate)cm×hcm
v=25(square)cm×6cm
v=625cm×6ccm
v=3,750cm(cube)
Answer:
4 then 6 then 8
Step-by-step explanation:
2×2=4
2×3=6
2×4=8
The expression 36x² - 121 is in the 'difference of two squares form' which is (a² - b²)
Factorising (a² - b²) gives (a+b)(a-b)
Factorising 36x² - 121 gives (6x+11)(6x-11)
