Answer:
2 real roots: x = -2 multiplicity 2.
Step-by-step explanation:
The discriminant = b^2 - 4ac
= 16^2 - 4*4*16
= 0
This means there are duplicate roots, 2 roots having the same value.
4x^2+16x+16=0
(2x + 4)(2x + 4) = 0
x = -2 , -2.
One – hundredth is fraction that can
also be written in decimal form. The fraction form is 1/00, while the decimal
form is 0.01. so the description of the one hundredth of 36 can be solved by multiplying
it by 0.01

Answer:
C.) 418 cm²
I hope this helped you : )
Step-by-step explanation:
First, you find the area of the square:
19 cm x 19 cm = 361 cm
Next, you find the area of the triangle:
(19 cm x 6 cm) ÷2 =57 cm
Last, you add the two:
361 cm + 57 cm = 418 cm²
Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
a = 0.1x
b = 0.2y
(0.1x - 0.2y)²= (0.1x)² - 2*0.1x*0.2y + (0.2y)²
= (0.1)²x² - 0.04xy + (0.2)²y²
= 0.01x² - 0.04xy + 0.04y²
