The factorisation of 10xᴧ2 – 18xᴧ3 + 14xᴧ4 is

ikadub [295]

Answer:

${10x}^{2} - 18 {x}^{3} + {14x}^{4} \\$

factorise out x² :

$= {x}^{2} (10 - 18x + 14 {x}^{2} )$

then factorise out 2:

$= 2 {x}^{2} (7 {x}^{2} - 9x + 5)$

Help (this for a friend)<br> a 62.1<br> b 117.4<br> c 122.1<br> d 164.5

kramer

Answer:

c. 122.1 cm

Step-by-step explanation:

so l * w + $\frac{\pi r^2}{2}$

since 6 cm is the diameter

6/2 = 3

the radius (or r) is 3

so 18 * 6 + $\frac{3.14 * 3*3}{y}$

108 + $\frac{3.14*9}{y}$

108 + $\frac{28.26}{2}$

108 + 14.13 = 122.13

simplified: 122.1 cm

hope this helps:)

Can you help me solve y=-3x-2 (-7x-6y=-10

navik [9.2K]

$y=-3x-2\\-7x-6y=-10\\\\
-7x-6(-3x-2)=-10\\
-7x+18x+12=-10\\
11x=-22\\
x=-2\\\\y=-3\cdot(-2)-2\\y=6-2\\y=4$

Maria mixes \frac{1}{4} cup white sugar and \frac{2}{3} cup brown sugar to make a topping for some muffins. She uses \frac{1}{12

Hoochie [10]

Answer: 11 muffins

Step-by-step explanation:

Since Maria mixes 1/4 cup white sugar with 2/3 cup brown sugar, this will give us a mixture of:

= 1/4 + 2/3

= 3/12 + 8/12

= 11/12

Ww are then told that she uses 1/12 cup of the mixture to top each muffin. Therefore, the number of muffins that she can top will be:

= 11/12 ÷ 1/12

= 11/12 × 12/1

= 12

She can top 11 muffins.
