You deposit $250<span> into a bank account paying </span>3%<span> simple interest per </span>year<span>. You left the money in for </span>30 years<span>. Find the interest earned and the amount at the end of those </span>30 years, <span>The interest is </span><span>$225 </span><span>and the amount is </span>$475 that is the answer.
So, to factorise something you are taking out the highest common factor.Here, 10 is an example of the highest common factor (I’ll refer to this as HCF)
10(2k+5)
Everything inside the brakets is multiplied by what’s directly next to it (if there is a negative sign, then that is included). So, 10 x 2k = 20k and 10 x 5 = 50
10(2k + 5) is the factorised version of 20k + 50
Answer:
15x5−x4−2x3+21x2+7x
Step-by-step explanation:
=(3x2+x)(5x3+−2x2+7)
=(3x2)(5x3)+(3x2)(−2x2)+(3x2)(7)+(x)(5x3)+(x)(−2x2)+(x)(7)
=15x5−6x4+21x2+5x4−2x3+7x
=15x5−x4−2x3+21x2+7x
Answer: x=10
Step-by-step explanation:
3x+2/24=12/9
9(3x+2)=288
27×+18=288
-18
27x=270/27
x=10
