IJ=x-4
JK=5x+12
IK=9x-19
IJ+JK=IK
(x-4)+(5x+12)=(9x-19)
x-4+5x+12=9x-19
6x+8=9x-19
6x+8-6x+19=9x-19-6x+19
27=3x
3x=27
3x/3=27/3
x=9
IJ=x-4=9-4→IJ=5
JK=5x+12=5(9)+12=45+12→JK=57
IK=9x-19=9(9)-19=81-19→IK=62
Answer: Option B. IJ=5, JK=57, IK=62
ANSWER
EXPLANATION
We want to add the two numbers:
0.82 + 0.35
Using the long addition method, we have:
0 . 8 2
+ 0 . 3 5
Start on the right hand side:
Answer:
16a^2 + 4a or 4a(4a+1)
Step-by-step explanation:
Use the distributive property (or FOIL).
First, the 3a2 becomes 6a.
6a x 4a = 24a^2
4a x -2a = 8a^2
4a x 1 = 4a
Simplify.
24a^2 - 8a^2 + 4a
=16a^2 + 4a
Other options:
=16a^2 + 4a
=4a(4a+1)
Hope this helped.
Answer:
x=13° & y=74°
Step-by-step explanation:
y=74°(cointerior angle r equal)
now,
y=4x+22(vertically opposite angles equal)
