671.34mm2
Step-by-step explanation:
area=base times height
A = bh thus: A=671.34 mm²
Area =b* (base) h (Height)
First ones 90 and the second one is 48
please brainliest me
5×16=80
80-12=68
n=68
x^2 +4x+4 = 4
To complete the square take the coefficient of the x term
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add it to both sides of the equation
