## Hassan M.'s Resources Step 1: Set length = x Step2: Width = 2x-7 Step 3: Area = 145 cm^2 = length * width = x(2x-7) Step 4: 2(x^2)-7x = 145 cm^2 Step 5: 2(x^2)-7x-145=0 Step 6: Use quadratic equation to solve for x Step 7: x=10.44266932535685 cm Step 8: Set diagonal = d Step 9: Use Pythagorean... Question: Solve the expression 110 times 10 + 5 - 2 times 7 + 4.   Comments: This question needs to be specified further for you could get two different solutions for it.   Solution 1: First, rewrite the expression and then use order of operations. Hence... This question is really vague because it should be presented in either of two ways to avoid confusions.   3/x + 3/2x = 2   1: 3/(x+3)/(2x)=2 ->3/((2x^2)+6x)=2 ->3/2=(2x^2)+6x ->(2x^2)+6x-1.5 -> use quadratic formula to solve... 1+2*2+3*3+4*4=1+4+9+16=30 The sum (total) is 30 Okay so many students face the difficulty of figuring out which word on a reading is the noun, pronoun, verb, adverb, and adjective. To avoid such confusions and to make educated guesses, use the following tips.   There are 8 parts of speech (not 5)!   1. Noun: describes place, person, or thing 2. Pronoun: modifies the noun 3. Verb: describes action or being 4... read more 1 meter = 3.28 ft 1 inch = 25.4 millimeter 4.92 inches = 25.4 * 4.92 millimeter = 124.968 millimeter Thus 4.92 in = 124.968 mm (6x4)(3x2)= (6)(3)(x4+2)=18x6   There are many other ways to go about such problems but this one's the simplest 20/√15 = 5.163977794943222 which is approximately 5.164 (20/√15)2 = 400/15 = 80/3 = 26.667 => √26.667 is approximately 5.164   Hope this helped.
