Answer:
The hight of the box is 1.2 m
Step-by-step explanation:
250cm= 2.5m
100cm= 1m
2.5x1=2.5
3/2.5=1.2
2.5 x 1 x 1.2=
Answer:
58
Step-by-step explanation:
1. let x be the unknown number
2. make an expression
x + 26/12 = 7/1
3. cross multiply
x +26 × 1 = x + 26
12 × 7 = 84
x + 26 = 84
4. move variables on one side and numbers on other side of the equal sign
x + 26 = 84
- 26 -26
x = 58
Answer:
AE =15
Step-by-step explanation:
BC=16-12 = 4
AE=x
12/4 = x/5
Cross multiplication
4x=60
x=15
4x3 = 12
5x3 =15
Answer:
X=5
move variable to the left side and change its sign.
move constant to the right side and change its sign
collect like terms x=4+1, add the numbers x=5
Step-by-step explanation:
<span>24x</span>³<span> - 54x</span>²<span> + 44x - 99 =
(24x</span>³ + 44x) - (54x² + 99) = <span>
4x</span>(6x²+11) - 9 (6x² + 11) =
(4x-9)(6x²+11)
Answer: (6x²+11)
