Is 5,840 estimate to 6,000 and 25 estimate to 30 which is 6,000 x 30 right

6*3=18

but 6000*30= 180000

so if estimate the answer it would be 20000

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

"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
