Answer:

use FOIL- Firsts Outsides Insides Lasts

  1. Multiply the -4 and -3 as they are the first numbers of each brackets -4x-3=12
  2. Next the outsides so -4x6i as they are on the outskirts of each brackets -4x6i= -24i
  3. Insides so 3i and -3 as they are in the centre of the two brackets 3ix-3= -9i
  4. Lasts so 3i and 6i as they are at the end of each bracket 3ix6i=18i^2 ( i squared)
  5. add the answers together - 12+-24i+-9i+18i^2= 12-24i-9i+18i^2
  6. Simplify by adding like terms which is -24i and -9i.
<h3>12+-33i+18i^2 is the answer </h3>

What is the width of a rectangle prism with the length of 13 feet volume of 11,232 ft.³ and height of 36
vekshin1
To get the volume of a rectangular prism, you multiply the base times the height by the width, so to get the width you would divide 11,232 by 13 which is 864, then you divide that by 36 to get 24, so the width would be 24.

What is the measure of X! Please help if you know how to do this!
deff fn [24]

Answer:

28°

Step-by-step explanation:

You're given that line DE and line FG are parallel and KL and FG are perpendicular. Then you can find out angle ∠BAC by using the vertical angles property: ∠BAC=62°. Then since KL and FG are perpendicular ∠ABC = 90°. So you find the angle ∠BCA by finding the sum of interior angles: 62+90+∠BCA=180, therefore ∠BCA is 28°. Finally, ∠x or ∠JCG = 28 because ∠JCG and ∠BCA are vertical angles and congruent.
