Which equation has no solution?
a. 7v + 2 = 8v - 3
b. 3x - 5 = 4y - 6
c. 4y + 5 = 4y - 6
d. 7z + 6 = -7z - 5

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

"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

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)
