There are 108 inches in 9 feet but there are 5 so 108×5= 540 so to get your answer you need to divide that by 15 which equals 36. so you can make 36 pieces

Factorise 2x²-9x+10 (this must be put in two brackets)
galben [10]
Find both roots :
\Delta=81-80=1 hence r=\frac{9\pm1}4=\frac{5}2\text{ or }2

Thus it is 2(x-\frac{5}2)(x-2)

Which expression is equivalent to (81x4y16)12 for all positive values of x and y?<br> 40.5x4y16
IrinaVladis [17]

Answer:

(81x^4y^{16})^{\frac{1}{2}} = 9 x^2 y^8

Step-by-step explanation:

Given

(81x^4y^{16})^{\frac{1}{2}}

Required

Determine an equivalent expression

Express 81 as 9^2

(9^2x^4y^{16})^{\frac{1}{2}}

Apply law of indices

9^2^{\frac{1}{2}} * x^4^{\frac{1}{2}} * y^{16}^{\frac{1}{2}}

9^{\frac{2*1}{2}} * x^{\frac{4*1}{2}} * y^{\frac{16*1}{2}}

9^{\frac{2}{2}} * x^{\frac{4}{2}} * y^{\frac{16}{2}}

9^1 * x^2 * y^8

9 * x^2 * y^8

9 x^2 y^8

Hence:

(81x^4y^{16})^{\frac{1}{2}} = 9 x^2 y^8
