Hello :
answer : <span>B (5x - 3)(2x - 1)
because : </span>(5x - 3)(2x - 1) = 10x²-5x-6x+3 = 10x²-11x+3
Answer:
28 feet
Step-by-step explanation:

In mathematics, the reciprocal, or multiplicative inverse, of a number x is the number which, when multiplied by x, yields 1. It is denoted 1/x or x-1.
Answer:
Step-by-step explanation:
Question 1:
First, write the equation out:
4(x+3)=7x-3
solve for x:
4x+12=7x-3
15=3x
x=5
Question 2:
Do the same on the second question:
30-x=3x-6
36=4x
x=9
Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm
Area of the top = area of the base = 64.5cm
Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm
Total surface area = 64.5 + 64. 5+ 330 = 459 cm²
------------------------------------------------------------------------
Answer: Total surface area = 459 cm²
