Answer:
x = 4.2
Step-by-step explanation:
tan 30° = x/7
tan 30° = 0.6
0.6 = x/7
7*0.6 = x
4.2 = x
Step-by-step explanation:
- according to bodmas .... brackets come first so the numerator (2-7)²+5 is 2-7= -5² hence -25 +5
- so the answer to the numerator becomes -25 +5 which is -20
- so u get -20/3 which when simplified u will obtain -6 and 2/3
28x4=112
112+49=161
Carlos will spend a total of $161 this year
Step-by-step explanation:
f(x) = -7x² - x
g(x) = 9x² - 4x
(f - g)(x) = (-7x² - x) - (9x² - 4x)
(f - g)(x) = (-7x² - 9x²) + (-x + 4x)
(f - g)(x) = -16x² + 3x
(f - g)(1) = -16(1)² + 3(1)
(f - g)(1) = -16.1 + 3
(f - g)(1) = -16 + 3
(f - g)(1) = -13
