2(7x - 3) = 9
step 1 : distribute thru the parenthesis......14x - 6 = 9
step 2 : add 6 to both sides.......14x = 15
Do 2*3 then do the answer divided by 18 to get the answrr
Answer:
15
Step-by-step explanation:
you have to multiply first because of the order of operations, so 2 × 3 = 6, and 6 + 9 = 15
The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter
