Answer:
6a³
Step-by-step explanation:
a⁴ + 9a³ - 10a² + 8a⁴ + X + a = 9a⁴ + 15a³ - 10a² = a
9a⁴ + 9a³ - 10a² + X + a = 9a⁴ + 15a³ - 10a² = a
9a³ + X + a = 15a³ = a
6a³ = X
checking: a⁴+ 8a⁴ + 6a³ = 15a³
9a⁴= 9a³
= a
Answer:
2.25
Step-by-step explanation:
2.4 - 0.15
Using place value :
2 = Unit (2 wholes)
4 = tenth place ( 4 tenths)
To subtract 0.15
0 wholes ; 1 tenth ; 5 hundredth
1 tenth can be split into 10 separate hundredths
Hence,
For 2.4
We have ;
2 wholes ; 3 tenths and 10 hundredths
Subtracting 0.15 ;0 wholes ; 1 tenth ; 5 hundredth
(2 - 0) wholes = 2 whole
(3 - 1) tenth = 2 tenth
(10 - 5) hundredth = 5 hundredth
Hence, the difference between (2.4 and 0.15) is :
2 whole ; 2 tenth ; 5 hundredth
Which is equal to : 2.25
Answer: 16x + 16
(2x+4)² is the large square ; (2x)² is the small square
the area of the colored figure in a letter phenomenon is
(2x + 4)² - (2x)² = 4x² + 16x + 16 - 4x² = 16x + 16
Step-by-step explanation:
Answer:
