As shown in the diagram of the right triangles below, triangle: abc ~ triangle: def, ab = 7x, bc = 4, de = 7, ef = x. what is thr perimeter of triangle: def to the nearest hundredth?

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

Divide. –4.2 ÷ 6 = a –0.7 b 0.7 c –7 d 7 me

Apolygon is shown on the graph: a polygon is shown on the coordinate plane. vertices are located at 3 comma 5, 1 comma 3, 1 comma 1, 2 comma 0, 4 comma 0, 5 comma 1, and 5 comma 3. what effect will a translation 3 units down and 2 units left have on the polygon? be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image. xd i need
