Answer
B) x + 20 ≥ 50
Step-by-step explanation:
Answer:
1) -6
2) x = -y +7 if you set all terms equal to zero.
Step-by-step explanation:
1) Isolate x by dividing -42 by 7. x = -6
2) Set the entire expression equal to zero.
x + y -7 = 0
Isolate x on one side of the equation. Remember to change signs when moving terms across the equal sign.
x = -y +7 if the original expression is set equal to zero.
Answer:
cos0 = 6.8556546i/23 or sqrt-47/23
Step-by-step explanation:
hypotenuse is 23, opposite is 24
we have to find the adjacent using the pythagorean theorem
24^2 + b^2 = 23^2
576+b^2=529
subtract
b^2=-47
b=sqrt-47
sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>
cos = adjacent/hypotenuse
The area of a square is Side x Side. Since its sides are equal you have:
S*S = 1.69
S^2 = 1.69
S = √(1.69)
S= 1.3 km
Hope this help :).
Answer: (4x + 3) (x + 2)
Step-by-step explanation:
We can rewrite 4x² + 11x + 6 as 4x² + 8x + 3x + 6
Since 4x² + 11x + 6 = 4x² + 8x + 3x + 6
= (4x + 3) (x + 2)
