Answer:
You just have to combine terms
Step-by-step explanation:
10h + 6 - 5h +3 can be written as:
10h - 5h + 3 + 6 (now all you have to do is combine terms)
<u>5h + 9</u>
Answer:
undefined / no solution
Step-by-step explanation:
10p - 2(3p-6) = 4(3p-6) - 8p
10p - 6p - 12 = 12p - 24 - 8p
4p - 12 = 4p - 24
0 = -12
0 cannot equal -12
The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
2(5*4)+2(4*3)+2(3*5)=94 sq.m (Orginial SA)
2(4*5)+2(5*6)+2(6*4)=148 sq.m (Total SA)
148-94=54 (New SA)
