Answer:

. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2) Step-by-step explanation:

Let a⃗ =4ı^−2ȷ^, b⃗ =−3ı^+5ȷ^, and e⃗ =2a⃗ +3b⃗ . part a write vector e⃗ in component form.
ch4aika [34]

We have been given that:

Vector \vec{a}=4\hat i-2\hat j and \vec{b}=-3\hat i+5\hat j.

Component form of a vector implies to write the vector with each individual components.

Now, our vector \vec e is given by

\vec e =2\vec a+3\vec b

Now, 2 \vec a=2(4\hat i- 2 \hat j)=8 \hat i -4 \hat j

and 3 \vec b= 3(-3 \hat i +5\hat j)=-9 \hat i + 15\hat j

Plugging the values  of 2 \vec a and 3\vec b, we get:

\vec e = 8 \hat i-4 \hat j-9 \hat i + 15 \hat j=- \hat i+11 \hat j

So, the vector 'e' in its component form is given as:

\vec e= -\hat i+11\hat j

Add the sum of 1 and one nineth part of 72 to the sum of 72 and one fourth of 72.​
meriva

Answer:

99

Step-by-step explanation:

1/9 of 72 = 8

1/4 of 72 = 18

1 + 8 = 9

72 + 18 = 90

90 + 9 = 99

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
