Answer:

(5x + 7y)² = 25x² + 70xy + 49y²

Step-by-step explanation:

(5x + 7y)² = 25x² + 70xy + 49y²

Because,

(5x + b)² = (5x)² + 2(5x)(b) + b²

2(5x)(b) = 70xy

b = 7y

b² = (7y)² = 49y²

-4n-4+n+8=-6(-2n-4)+5(5-3n)
IgorC [24]

Answer:

There are no possible solutions BROTHER

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−4n−4+n+8=−6(−2n−4)+5(5−3n)

−4n+−4+n+8=(−6)(−2n)+(−6)(−4)+(5)(5)+(5)(−3n)(Distribute)

−4n+−4+n+8=12n+24+25+−15n

(−4n+n)+(−4+8)=(12n+−15n)+(24+25)(Combine Like Terms)

−3n+4=−3n+49

−3n+4=−3n+49

Step 2: Add 3n to both sides.

−3n+4+3n=−3n+49+3n

4=49

Step 3: Subtract 4 from both sides.

4−4=49−4

0=45

Are the ratios 2:1 and 19:10 equivalent?
Oduvanchick [21]

Answer:

No.

Step-by-step explanation:

2:1 and 19:10 are not equivalent.

Simply, because if you divide 9 by any number with the 10, it is not going to stay as a whole number. For example, 19 divided by 2 equals 9.5. 19 divided by 5 equals 3.8. So, no they are not equivalent.
