2y^2-7y+6= 2y^2-4y-3y+6

an architect wants to build three similar triangles such that the ratio of the middle triangle. The smallest one has side length

vampirchik [111]

Answer: 15

Step-by-step explanation:

small: 5 12 13

middle: __ 36 39

large: 45 108 117

Notice that to get from the small to the large, multiplied by 9

5(9) = 45 12(9) = 108 13(9) = 117

That is because the sides are proportional $\dfrac{5}{45}=\dfrac{12}{108}=\dfrac{13}{117}\rightarrow\dfrac{1}{9}$

To get from small to middle, multiply by 3

5(3) = 15 12(3) = 36 13(3) = 39

To solve it using proportions:

$\dfrac{5}{x}=\dfrac{12}{36}\\\\\\\text{Cross Multiply and solve for x:}\\5(36)=12x\\\\\dfrac{5(36)}{12}=x\\\\5(3)=x\\\\\large\boxed{15}=x$

Write down a division with an answer of 0.713

chubhunter [2.5K]

Notice, 3 decimals, so, we can just use 3 zeros, thus

$\bf 0.\underline{713}\implies \cfrac{0713}{1\underline{000}}\implies \cfrac{713}{1000}\implies 713\div 1000$
