Answer:
5(x-3)
Step-by-step explanation:
The word "SUM" means the answer to an "ADDITION".
"SUM" is always used with the word "AND" to indicate which numbers are being added.
The SUM of a number AND -3 is written as:
(
x
+
(
−
3
)
),
or (
x
-3
)
(where we have chosen the number to be x
.)
But we want FIVE of those sums; this means:
5 (
x
−
3
)
The answer is 15. just replace the letters with the numbers they're equal to.
Answer:
60
Step-by-step explanation:
You would just plug everything in so you get -5(-2-(-5)(-2)) which can be reduced so -5(-12) which is 60
Answer:
EAC LINE TO~triangle BDC
Step-by-step explanation:
B AND D IS NOT UQAUL
AEC IS THE FIRST GIVEN
SO YOU FINE THE ALL RIGHT ANGLES RIGHT
4x + 2x = < y
This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).
We have to find X.
As you know:

because the angles of a triangle add up to 180.
When we add them:


The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

Substitute value of x into 4x and 2x to find the exterior angle:-
4x:

2x:

When we add them we get the answer for angle Y:-

Therefore, we can conclude that:
