15x-20<130
15x<130+20
15x<150
X=150/15
x<10
Answer:
4x+7z
Step-by-step explanation:
4x + 2z + z +4z is the expression
The simplified expression is just the terms combined
so,
4x + 2z+1z+4z
4x+3z+4z
4x+7z
There aren't any like terms so it would be
x+2y+3z
9.60 times 10 squared is the answer
In the the figure above AC bisects BCD in the quadrilateral, the length of CD will be 6cm.
<h3>How to calculate the value?</h3>
It should be noted that the longer diagonal is a perpendicular bisector of the shorter diagonal.
From the diagram given, the value of AD is 6cm. Therefore, according to the angle bisector theorem, the value of CD is 6cm as they're congruent.
