Hello hope your day is well i really need help with this expand question 4(a+5)-2(a-5)
2 answers:
Answer:
2a + 30
Step-by-step explanation:
use the distributive property:
4<em>a</em> + 20- 2<em>a</em> + 10
then rearrange for like terms
4<em>a</em> - 2<em>a</em> + 20 + 10
then add it up
2<em>a </em>+ 30
Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30
if anything doesnt seem right just comment and i will correct

Answer: I'm not entirely sure, but maybe 1/x^2?
Step-by-step explanation:
WE know
- A=P(1+r/n)^nt, where A is the amount, P is the principle r is the rate , t is the time and n is the number of interest compounded per unit time
so by suing this formula
- A=40000(1+0.1/2)^2*2
- A=40000(1.2155)
- or, A=48620.25
- therefore the amount is Rs.48620.25
The answer is (2x+5)^2
Have a nice day
