What are the roots of the equation? x^2+24=−11x Enter your answers in the boxes.

docker41 [41]

The correct answers are:

x=-3 and x=-8.

Explanation:

We can first write this in standard form, ax²+bx+c=0. To do this, we will add 11x to both sides:
x²+24+11x=-11x+11x
x²+11x+24=0.

Now we can factor this. Look for factors of c, 24, that sum to b, 11. Factors of 24 are:
1 and 24 (sum 25)
2 and 12 (sum 14)
3 and 8 (sum 11)
4 and 6 (sum 10).

The factors we need are 3 and 8, since they sum to 11. This gives us factored form:
(x+3)(x+8)=0.

Using the zero product property, we know that in order to have a product of 0, one or both of the factors must be 0. This means we have:
x+3=0 or x+8=0.

Solving the first equation:
x+3-3=0-3
x=-3.

Solving the second equation:
x+8-8=0-8
x=-8.

Which of the following is equivalent to -2/3?

arlik [135]

Answer:

Step-by-step explanation:

-2/3 = -4/6 = -6/9 = -8/12

= -10/15 = -12/18 = -14/21 = -16/24

= -18/27 = -20/30 = -22/33 = -24/36

= -26/39 = -28/42 = -30/45 = -32/48

= -34/51 = -36/54 = -38/57 = -40/60

= -42/63 = -44/66 = -46/69 = -48/72

= -50/75 = -52/78 = -54/81 = -56/84

= -58/87 = -60/90 = -62/93 = -64/96

= -66/99 = -68/102 = -70/105 = -72/108

= -74/111 = -76/114 = -78/117 = -80/120

= -82/123 = -84/126 = -86/129 = -88/132

= -90/135 = -92/138 = -94/141 = -96/144

= -98/147 = -100/150 = -102/153 = -104/156

= -106/159 = -108/162 = -110/165 = -112/168

= -114/171 = -116/174 = -118/177 = -120/180

= -122/183 = -124/186 = -126/189 = -128/192

= -130/195 = -132/198 = -134/201 = -136/204

= -138/207 = -140/210 = -142/213 = -144/216

= -146/219 = -148/222 = -150/225 = -152/228

= -154/231 = -156/234 = -158/237 = -160/240

= -162/243 = -164/246 = -166/249 = -168/252

= -170/255 = -172/258 = -174/261 = -176/264

= -178/267 = -180/270 = -182/273 = -184/276

= -186/279 = -188/282 = -190/285 = -192/288

= -194/291 = -196/294 = -198/297 = -200/300
