There are infinite expressions equal to 0.09*0.4, but I will right a few
(this equation equals 0.036
1. 0.009*4
2. 9*0.004
3. 0.06*0.6
The answer is 15, hope this helps
Step 1: <span>Rewrite the decimal number as a fraction with 1 in the denominator.
Step 2: </span>Multiply to remove 10 decimal places. Here, you multiply top and bottom by 10 to the power of 10<span> = 10000000000
Step 3: Find the GCF of 476190476 and 10000000000 </span><span>if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4.
</span>Step 4:<span> denominator by GCF = 4,</span><span><span><span><span>476190476÷4</span><span>10000000000÷4</span></span>=<span>1190476192500000000</span></span><span><span><span>476190476÷4</span><span>10000000000÷4</span></span>=<span>1190476192500000000</span></span></span>Therefore<span><span>X=<span>119047619/2500000000</span></span><span>X=<span>1190476192500000000</span></span></span>In conclusion,<span><span>.0476190476=<span>119047619/2500000000</span></span></span>
5x^2-8x+5=0
ax^2+bx+c=0; a=5, b=-8, c=5
Quadratic Formula:
x=[-b+-sqrt(b^2-4ac)]/(2a)
x=[-(-8)+-sqrt( (-8)^2-4(5)(5) )] / [(2)(5) ]
x=[ 8+-sqrt(64-100)] / 10
x=[ 8+-sqrt(-36)] / 10
x=[8+-sqrt( (36)*(-1)) ] /10
x=[8+-sqrt(36)*sqrt(-1)] / 10
x=(8+-6i) / 10
x=(8/2+-6i/2) / (10/2)
x=(4+-3i)/5
x1=(4-3i)/5
x2=(4+3i)/5
Answers:
x=(4-3i)/5 , x=(4+3i)/5
