Evaluate. <br> 6[5(3-9)-1]+2/7(8-2)+4

GREYUIT [131]

If you would like to evaluate 6 * [5 * (3 - 9) - 1] + 2 / 7 * (8 - 2) + 4, you can calculate this using the following steps:

6 * [5 * (3 - 9) - 1] + 2 / 7 * (8 - 2) + 4 = 6 * [5 * (-6) - 1] + 2/7 * 6 + 4 = 6 * [- 30 - 1] + 12/7 + 4 = 6 * [- 31] + 12/7 + 4 = - 186 + 12/7 + 4 = - 182 + 12/7 = - 1274/7 + 12/7 = - 1262/7

The correct result would be - 1262/7.

ILL MARK BRAINILEST !! 80 POINTS

$\\ \rm\rightarrowtail y=x^2-10x+16$

$\\ \rm\rightarrowtail y=x^2-10x+16+9-9$

$\\ \rm\rightarrowtail y=x^2-10x+25-9$

$\\ \rm\rightarrowtail y=(x-5)^2-9$

Vertex form

y=a(x-h)^2+k

So

vertex:-

(h,k)=(5,-9)

NEED HELP WITH A MATH QUESTION

Lady_Fox [76]

Answer:

$\dfrac{18}{5}$

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

$\dfrac{18}{5}$
