Answer:
7*40=7 group of 4 ten
7 groups of 4 tens=28 tens
28 tens = 280 seats on the bus
Step-by-step explanation:
A school has 7 buses. Each bus has 40 seat
1 bus = 40 seat
To find the number of seats on 7 buses we multiply the number seat of each bus with total number of buses
7 buses = 40 * 7 = 280
40 can be written as 4 tens
7*40=7 group of 4 ten
7 groups of______tens= ________tens
7 group of 4 tens
we add 7 groups of 4 tens , 4 +4+4+4+4+4+4 = 28 tens
7 groups of___4___tens= ____28____tens
_____tens = _____ seats on the bus
28 tens = 28 * 10 = 280 seats on the bus
Answer:
4
Step-by-step explanation:
y² − 4y = 3
y² - 2*2*y =3
y² - 2*2*y + 2² = 3 + 2²
(y - 2)² = 3 + 4
Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2
Hope it helped!
