Answer:
5x - 18
Step-by-step explanation:
-3(x + 6) + 8x
Multiply
(-3 * x) + (-3 * 6) + 8x
-3x + (-18) + 8x
5x - 18

Step-by-step explanation:
In construction, we use trigs. For figuring areas of triangular shapes ( gabled roofs and exterior wall cladding). Similar to many concepts and phenomena in Maths, it can be found in many aspects of life if we observe and examine carefully.
Please, one problem at a time. Haven't you started any of these?
What is a+b? Write out a and b, one over the other, and then combine like terms:
1i + 4j
-4i - j
-----------
-3i + 3j (answer to "a+b").
Please try some of the other problem, sharing your work or at least asking questions whose answers might help you get started.
You can create a right angled triangle.
Find the hypotenuse.
The third point of the triangle is (1,0)
using pythagoras, the value of a is 2, b is 3. 2^2 +3^2 = 13.
Therefore the distance between the two points is
An easy one for that would be 2x23= 46
Hope it helps!
