Answer:

-2j + 11k

Step-by-step explanation:

4v + 3w

4[3i – 2j + 5k] + 3[- 4i + 2j – 3k]

= 12i - 12i - 8j + 6j + 20k - 9k

= 0i - 2j + 11k

Answer:

answer will be -2j+11k

expln: 4v+3w

=4(3i-2j+5k)+3(-4i+2j-3k)

=12i-8j+20k-12i+6j-9k

=(12-12)i+(-8+6)j+(20-9)k

= -2j+11k :)

Answer:

D.

Step-by-step explanation:

h(x)=f(x)g(x) means multiply the expression for f to the expression for g.

That is the problem is just asking you to do (11x-5)(-2x-4).

Let's use foil.

First:  11x(-2x)=-22x^2

Outer: 11x(-4)=-44x

Inner: -5(-2x)=10x

Last: -5(-4)=20

------------------------Add together!

-22x^2-34x+20

A toolbox contains a pile of mixed up pile of wrenches. The wrenches are all labeled with the dimension of their openings in fra
Sergio039 [100]
1.

     a)Two different methods for ordering these wrenches are either
     converting the measurements into decimal or converting them into
     fractions. 

     b) I chose to convert them into fractions with an LCD of 16. The fractions
     are: 8/16, 12/16, 6/16, 10/16, 5/16, 7/16, 11/16

     c) The ordered form of the fractions, from least to greatest, is 5/16, 3/8,
     7/16, 1/2, 5/8, 11/16, 3/4

2. I don't see how I can put them on a number line. 

3. The number line can definitely be used to support the answer from part C (if it is done correctly). That is because if the order on the number line is the same as the order in C, then we know that C is correct. In addition, since the number line includes benchmarks, we can easily see if the answer to C is incorrect.

Again one question not two
Anettt [7]

Answer: A) 5m = 50; m = 10

Step-by-step explanation:

The diagram shows 5 "m"s, or 5*m equal to 50.  Thus, 5m=50.

Because 5m = 50, divide both sides by 5 to get that m = 10
