Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
You do cross multiplication so multiply 29 by 38 and then divide it by 78 which gives you answer of 14.128 cm
