Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
Answer:
a
b
d
Step-by-step explanation:
im to lazy but subtract 180 and the others are equal just compare small angles to big ones and should equal 180
The next time this will happen again is when its turn 11:11
A^4-6a^2-8 is the write answer
option c
just open the brackets and then add and subtract
according to PEMDAS rule or DMAS
