LAST QUESTION PLEASE HELP!!

Which expression would find the area of this figure?

split the figure into two parts

1st part is 7 × (12-3)

2nd part is 3×4

(9×7) + (3×4)

13.46

step-by-step explanation:

16.80 x .20 = 13.46

"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
