(4x ^3 + 7y ^3z ^4) ^2

16 + 56x³y³ + 49

Step-by-step explanation:

Note that we are using the rule of exponents

× ⇔

Given

(4x³ + 7y³ )² = (4x³ + 7y³ )(4x³ + 7y³ )

Each term in the second factor is multiplied by each term in the first factor, that is

4x³ (4x³ + 7y³ ) + 7y³ ( 4x³ + 7y³ ) ← distribute both parenthesis

= 16 + 28x³y³ + 28x³y³ + 49 ← collect like terms

= 16 + 56x³y³ + 49

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
