A = lw - s²
A = (x + 10)(2x + 5) - (x + 1)²
A = (x(2x + 5) + 10(2x + 5)) - (x + 1)(x + 1)
A = (x(2x) + x(5) + 10(2x) + 10(5)) - (x(x + 1) + 1(x + 1))
A = (2x² + 5x + 20x + 50) - (x(x) + x(1) + 1(x) + 1(1))
A = (2x² + 25x + 50) - (x² + x + x + 1)
A = (2x² + 25x + 50) - (x² + 2x + 1)
A = (2x² - x²) + (25x - 2x) + (50 - 1)
A = x² + 23x + 49
Answer:
0.0671081 mph
Step-by-step explanation:
divide 3 cm/s by 44.704 to get mph
33 + x + 120 - 2x = 180
153 - 1x = 180
-1x = 180 - 153
-1x = 27
-1x/-1 = 27/-1
The answer is -27
Answer:
The numbers are 12 and 3.
Step-by-step explanation:
12+3=15
&
3×12= 36

F(-1)
replace all x with -1
f(-1)=-3(-1)^2+2(-1)-7
f(-1)=-3(1)-2-7
f(-1)=-3-9
f(-1)=-12
