Can anyone help! Can anyone help me with this question!

Step-by-step explanation:

The only difference between these two triangles is that they are rotated differently. If we line up their congruent sides we can see that BC is congruent to EF. EF is given to us, but BC is an equation. Since we know they are the same length, we can set them equal and solve for x.

Hope this helps!

answer: a

step-by-step explanation:

10.2 units

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
