Answer:

  4x²(x +6)

Step-by-step explanation:

The smallest coefficient, 4, is a factor of the largest, so that will be a common factor. All terms contain x to some power, the least of which is 2, so x² will be a common factor. Factoring those common factors out, we have ...

  = 4x²(x +6)

The factor x+6 cannot be factored further, so this is the full factorization.

Step-by-step explanation:

Looking at the graph, we can see that

A = (3, -3)

B = (10, -5)

C = (6, -8)

Reflecting over the y axis means reflecting over the big, bold vertical line in the middle. To do this for a point (x, y) simply means changing the x value to -x. For example, to reflect (6, 7) over the y axis, we would turn it into (-6, 7)

A' = (-3, -3)

B' = (-10, -5)

C' = (-6, -8)

Plot these points on the graph and connect them to get your new triangle

Find the value(s) of k for which the expression is a perfect square trinomial.
49x^2-84x+k

Answers

Step-by-step explanation:

step 1. the perfect square will look like this: (7x + a)(7x + a) = (7x + a)^2.

step 2. by performing FOIL you will get 49x^2 + 14xa + a^2.

step 3. 14a = 84. a = 6

step 4. a^2 = 36.

step 5. k = 36.

Students reported volunteering at the animal shelter during the last 6 months for 25, 36, 31, and 32 hours. What is the mean absolute deviation for the number of hours students volunteered? Round to the nearest tenth.0

Answers

The correct answer for the question that is being presented above is this one: "3"

(1) First get the mean: 25 + 36+ 31 + 32 / 4 = 31
(2) Find the distance of each value to the mean: 31-25= 6; 36-31=5; 31-31=0; 32-31=1
(3) Get the mean of the distance: 6 + 5 + 0 + 1 / 4 = 3

So the mean deviation is 3.

[(a+3)x8+26]:5=18 va multumesc frumos

Answers

[(a+3)*8+26]:5=18 \n\n (a+3)*8+26=18*5 \n\n (a+3)*8+26=90 \n\n (a+3)*8=90-26 \n\n (a+3)*8= 64 \n\n a+3=64:8 \n\n a+3=8 \n\n a=8-3 \n\n \boxed{a=5}
so [(a+3)8+26]/5=18
multiply out
[8a+24+26]/5=18
add
(8a+50)/5=18
bultiply both sides by 5
8a+50=90
subtract 50 from both sides
8a=40
divide both sides by 8
a=5
