Answer:
3m² + 2mn + 7n²
Step-by-step explanation:
Subtract m² + 3mn - n² from 4m² + 5mn + 6n², that is
4m² + 5mn + 6n² - (m² + 3mn - n²)
= 4m² + 5mn + 6n² - m² - 3mn + n² ← collect like terms
= 3m² + 2mn + 7n²
Anyway, the value of 5 is 50 and the value of 6 is 6 as in the ones place.
Answer: Carson's average points in each game = 122
Jana's average points in each game = 104.4
Step-by-step explanation:
By the given table,
1) The total points Carson get in the game = 366,
He played games = 3,
⇒ His average point in each game = Total points he get/ total game he play
= 366/3
= 122
2) Now, The total points Jana get in the game = 522,
She played games = 5,
⇒ Her average point in each game = Total points she get/ total game she play
= 522/5
= 104.4
Answer:
The length if the garden is 21 meters.
The width of the garden is 5.25 meters.
If the scale changes to 1 cm : 9 meters, the new length of the garden is 63 meters and the new width of the garden is 15.75 meters.
The new length of the garden is 3 times as long as the original length of the garden.
Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
