Answer:
x = ± 7
Step-by-step explanation:
Given
(2x - 1)(3x + 2) = x + 292 ← expand left side using FOIL
6x² + x - 2 = x + 292 ( subtract x from both sides )
6x² - 2 = 292 ( add 2 to both sides )
6x² = 294 ( divide both sides by 6 )
x² = 49 ( take the square root of both sides )
x = ± 7
That is x = - 7, x = 7
Answer:
Step-by-step explanation:
First count the number of sides. There are 6 sides.
Now use the formula
(n - 2) * 180 To determine the total of all 6 angles.
(6 -2) * 180 =
4 * 180 = 720
Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.
x + 4 + 120 + x + 50 + 140 + 112 + x = 720 Combine
3x + 4 + 120 + 50 + 140 + 112 = 720
3x + 426 = 720 Subtract 431 from both sides
3x = 720 - 426 Combine
3x = 294 Divide by 3
x = 294/3
x = 98
Answer:
-22
Step-by-step explanation:
g(2-1)=g(1)=(2-g(2))/8=3
2-g(2)=24
-g(2)=22
g(2)=-22
Answer:
r < 3/2 or r < 1.5
Step-by-step explanation:
-8r - 9 > 21
-8r > -21 +9
-8r > -12
divide both sides by -8
= r < 3/2 or 1.5
Answer:
b
Step-by-step explanation:
90×(2)
= 180
each mile is equal to 90 calories
therefore 2 miles is equal to 180
