Factor 3h2 – 11h - 42

Mathematics
2 answers:
Zina [86]4 years ago

The answer is D
3*-42=-126
The factors of -126 that add to -11 are 7 and -18
replace -11h with 7h-18h
3h^2 + 7h - 18h - 42
Factor the first two terms and last two terms
h(3h+7) - 6(3h+7)
See how the two parentheses are the same?
THE ANSWER IS BELOW!!
(h-6)(3h+7)
the first parentheses has the terms that were outside, and the second has the original bracketed terms
This matches option D (it just multiplies the terms backwards, which gives the same result)

Answer:

The correct answer is option D. (3h + 7)(h – 6)

Step-by-step explanation:

It is given a quadratic function ,

3h² - 11h - 42

<u>To find the factors of given function</u>

3h² - 11h - 42  = 3h² - 18h  + 7h - 42

 = 3h(h -6) + 7(h - 6)

 =(h - 6)(3h + 7)

 = (3h + 7)(h – 6)

The correct answer is option D. (3h + 7)(h – 6)

Lelu [443]

Answer:

Let me know if you want more explanation

Step-by-step explanation:

Alright, to solve for x we need 2 angles that are congruent or equal.

I'm going to use the two we will need later. KLN and MNL

Now to find x ^^

2x-18=x+6\\2x-18-x=x+6-x\\x-18=6\\x-18+18=6+18\\x=24

Now we just need to plug it into each angle. I'm going to show you them separately.

KLN=2x-18\\KLN=2(24)-18\\KLN=48-18\\KLN=30

MNL=4x-6\\MNL=4(24)+6\\MNL=102

should be right now.

Can someone plz help me
Illusion [34]
First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:
l=3 unit
w=1 unit
h=5 unit.
V=l×w×h
V=3×1×5
V=15 cubic inches.

Second rectangular:
Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!

If the sales tax rate in Perryville
TEA [102]
To find the tax rate (in this case, 8%), you must multiply the base cost ($128) by the percentage (or, divide the cost by 100 and multiply that by the percentage).

$128÷100=$1.28

$1.28×8%=$10.24

So, the amount of tax that is charged on the table is exactly $10.24.

Hope this helps!
