Suppose the length is 7x, the width is then 3x
7x*3x=525
21x²=525
x²=25
x=5
so the length is 7*5=35, and the width is 3*5=15
It is on the ten thousands value

Answer:
a(
+
) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a(
+
)
Just substitute the values given for each variable
a(
+
) = (-1)(
+
) ; do the exponents first
a(
+
) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a(
+
) = -13 ; and multiply by -1
