Answer:
7x^2+2x-4
Step-by-step explanation:
a standard form is ax+by=c
5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4
Answer:
oiie4546
Step-by-step explanation:
90= 3x + 2x

one measure = 3(18)= 54
the other one= 2(18)= 36
hope this helps!
The values of the variables x, y and z are; 9, 81 and 6 respectively
<h3>Rhombus Diagonals</h3>
According to the question;
- All sides of the Rhombus are equal.
Hence, the Diagonals of the Rhombus are perpendicular bisectors of each other.
Therefore,
Angles 1, 2 and 3 are all equal to 90°, so that we have;
x = 9°
y = 81°
z = 6°
