Area of rectangle is the multiplication between the sides.
The first rectangle:
A = (2x + 5) . (3x - 2)
A = 2x . 3x - 2 . 2x + 5 . 3x - 2 . 5
A = 6x² - 4x + 15x - 10
A = 6x² + 11x - 10
The second rectangle:
A = (5y + 5) . (2y - 3)
A = 5y . 2y - 3 . 5y + 5 . 2y - 3 . 5
A = 10y² - 15y + 10y - 15
A = 10y² - 5y - 15
Answer:
26in^2
Step-by-step explanation:
5 time 4 is 20in^2. plus 2 times 3 is 6in^2.
add 20 and 6 then you get 26in^2.
Answer:
301.44
Step-by-step explanation:
4*4*3.14*2=100.48
8*3.14*8=200.96
100.48+200.96=301.44
Answer:
Where are the graph(s)?
Step-by-step explanation:
Answer:
1/(8a^12)
Step-by-step explanation:
(2a^4)^-3
Rewriting
2^-3 * a^4^-3
We know x^y^z = x^(y*z)
2^-3 * a^(4*-3)
2^-3 * a^-12
We know x^-y = 1/a^y
1/2^3 * 1/a^12
1/8 * 1/a^12
1/(8a^12)
