Answer B
Step-by-step explanation:
2x+1+14
Hello! For these types of inequalities, we put what’s in the middle to solve for the one behind and ahead. -3x + 12 is in the middle. Let’s solve it like this: x + 4 < -3x + 12. Add 3x to both sides to get 4x + 4 < 12. Subtract 4 from both sides to get 4x < 8. Divide each side by 4 to isolate the “x”. 8/4 is 2. x < 2. Now, let’s solve the other like this: -3x + 12 < 24. Subtract 12 from both sides to get -3x < 12. Divide each side by -3 to isolate the “x”. 12/-3 is -4. Because you divided by a negative, you flip the sign over into greater than. The solution to the compound inequality is -4 < x < 2, but none of the choices show that. In this case, the part of the solution is x < 2, so if you had to pick from one of the answers, the answer is C.
You cannot work this out without the angles
We are given two sides and their included angle. Using the side-angle-side method we can find the Area of the triangle using the following formula:
Area = 0.5 ab sin(γ)
a = Measure of first side = 3.2 feet
b = Measure of second side = 4.7 feet
γ = Angle between the two sides = 62 degrees
Using the values in the above formula, we get:
Area = 0.5 x ( 3.2) x (4.7) x (sin(62))
Area = 6.64 square feet (rounded to nearest hundredth)
Thus, the Area of the given triangle is 6.64 square feet
Your answer will be t=3k/v if you solve for t
