<em><u>Answer: x=-2 *The answer should be the negative sign.*</u></em>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
remove parenthesis
-15x-15*4=-30
15*4=60
-15x-60=-30
add 60 both sides of an equation.
-15x-60+60=-30+60
simplify.
-15x=30
divide by -15 both sides of an equation.
-15x/-15=30/-15
simplify.
30/15=2
x=-2
Hope this helps!
Thanks!
Have a great day!
Answer:
-12
Step-by-step explanation:
Step 1: Add 18 to both sides.
−2x−18+18=6+18
−2x=24
Step 2: Divide both sides by -2.
−2x
−2
=
24
−2
x=-12
Answer:
To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Step-by-step explanation:
:) Hope this helps you with what you're working on!
EF || AC ==》 180 - 4x = EBC ( ♡ )
_______________________
And also :
ABD = FBC ==》 FBC = x ( ☆ )
_______________________
EBC = EBF + FBC
( ♡ ) , ( ☆ ) :
180 - 4x = 65 + x
Subtract both sides 65
180 - 65 - 4x = 65 - 65 + x
115 - 4x = x
Add both sides 4x
115 - 4x + 4x = x + 4x
115 = 5x
Divide both sides by 5
115 ÷ 5 = 5x ÷ 5
23 = x

And we're done ...
