Answer:
x² + 2ax + a² + 5x + 5a + 4
Step-by-step explanation:
Formula -
( a + b )² = a² + 2ab + b²
Steps -
( x + a )² + 5 ( x + a ) + 4
x² +2ax + a² + 5 ( x + a ) + 4
x² + 2ax + a² + 5x + 5a + 4
The answer would 2.1
*start with -2.8d+2.8d (that would cancel would each other)
* 3.4 -1.3
* that would equal to 2.1
hope that helped
Answer:
= 50.6 miles per hour
Showing Work:
This is a fraction equal to
405 miles ÷ 8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8
405 miles ÷ 8
8 hours ÷ 8
=
50.625 miles
1 hour
=
50.625 miles
hour
= 50.625 miles per hour
rounding to the nearest tenth:
50.6 miles per hour
