Find the value of x, given that the triangles are similar. x = ?

x = 15  over4 ,  y≈ 9.8  units

Step-by-step explanation:

Since triangles ABC and DEF are similar, their corresponding sides are in the same ratio.

hope this helps!

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

7x7=4 so if u carry the 9 it will be 33
