dont click this one it is not the right answer
Answer:
x = 19°
Step-by-step explanation:
m∠DBA = m∠CBE = 71 because they are vertical angles
∠A and ∠DBA are complementary angles because the acute angles of a right triangle are complementary
So, m∠A + m∠DBA = 90
x + 71 = 90
x = 19°
Answer:
Step-by-step explanation:
Formula of a rectangle:
a = area
h = height
w = width (or base length)
Replace the variables with the numbers given:
Divide both sides by 4:
b = 12
Since 48 is the max, the number can only be equal to or lower than 12:
Answer:
the A is right
Step-by-step explanation:
We have (f+g)(x) = f(x) +g(x)
So f(x) + g(x) = 3x^2 + 2x – 1 and we know g(x) = 2x -2
or f(x) + 2x-2 = 3x^2 + 2x – 1
f(x) = 3x^2 + 2x – 1 - ( 2x -2)
f(x) = 3x^2 + 2x – 1 - 2x +2 \
finally
f(x) = 3x^2 + 1, and the A is right.
Have a good day
