Answer:
Step-by-step explanation:
Ethan, this is a quadratic equation. We should rewrite this in standard quadratic form: 4x^2 + 16x - 9 = 0. Let's use the quadratic formula approach to solve this:
The coefficients of x are a = 4, b = 16 and c = -9. Thus, the discriminant is
b^2 - 4ac, or 16^2 - 4(4)(-9), or 256 - 144, or 112.
The two solutions are real and are as follows:
-16 ± √112 -16 ± √(16*7) -16 ± 4√7
x = ------------------- = ----------------------- = -----------------
2(4) 8 8
Or, after simplification,
-4 ± √7
x = --------------
2
Answer:
44.5
Step-by-step explanation:
Multiplying 10 with 4.45 using mental math to find the total cost of 10 items. first multiply 0 with 445 which will yield 000, then multiply 1 with 445 which will yield 445 now put a cross beneath last 0 in 000 and write 445 before it and perform addition which will yield 4450 as the decimal was initially was before the second last digit in 4.45, place it accordingly in 4450 which will yield 44.5.
