D. 3 If you multiply each side of △ABC (ex: 5) by 3, you get the same side on △DEF
5x3 = 15
4x3 = 12
3x3 = 9
Step-by-step explanation:
no.C I think?............
Answer:
here down is the answer
(2y/5y)^3+4y^2+6y
8y^3/125y^3 +16y^2+6y
8/125+16y^2+6y
8/125+16y^2+6y=0
16y^2+6y+8/125=0
it is in the form of quadratic equation
formula :
x=(-b+-square root of b^2-4ac) /2a
here a=16,b=6&c=8/125
x=(-b+-square root of b^2-4ac)/2a
x=(-6+-square root of 36-4.09)/2a here 4.09 came by calculation
x=(-6+-31.91)/2
so
x=(-6+31.91)/2 first (+);
x=25.91/2
x=12.955;
x=(-6-31.91)/2 then(-);
x=-37.91/2
x=-18.955 ;
ans is = 12.955&-18.955;
The quotient of 2 3 / 5 ÷ 1 2 / 5 as a mixed fraction is 1 6 / 7
<h3>What is quotient?</h3>
Quotient is the answer obtained when we divide one number by another. Therefore,
2 3 / 5 ÷ 1 2 / 5
let's convert the mixed fraction to improper fractions.
2 3 / 5 = 13 / 5
1 2 / 5 = 7 / 5
Therefore,
13 / 5 ÷ 7 / 5 = 13/ 5 × 5 / 7
13/ 5 × 5 / 7 = 13 / 7 = 1 6 / 7
Therefore, the quotient of 2 3 / 5 ÷ 1 2 / 5 is 1 6 / 7
