The answer is A because the x repeated. ( the x I’m talking about is 2)
Answer:
∠DBC=120
Step-by-step explanation:
2x+(x+90)=180
2x+x+90=180
3x+90=180
3x=180-90
3x=90
x=90/3
x=30
blug x in to ∠DBC
∠DBC=30+90=120
Answer:
But it's not an exponential function. In an exponential function, the independent variable, or x-value, is the exponent, while the base is a constant. For example, y = 2x would be an exponential function.
Step-by-step explanation:
the normal exponential function is ab^x, where a represent the growth( sometimes you don't need this part), b is average rate of growth and x is the number of times we exponate. is a exponetital function because it includes the b and x part. The a part is someetimes used but not always.
Let the width be x.
Length = 5 + x
Perimeter = 58
2(l + w) = 58
2(5 + x + x) = 58
2(5 + 2x) = 58
10 + 4x = 58
4x = 48
x = 12
Hence, the length is 17 cm and the width is 12 cm.
