Answer:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.
When a tangent line (13.5 cm) and a secant (lines x + 8.45 cm) intersect then:
tangent line^2 = 8.45 * (8.45 + x)
13.5^2 = 71.4025 + 8.45 x
182.25 -71.4025 = 8.45x
8.45 x = 110.8475
x = 13.1180473373
x = 13.1 (rounded)

Answer:
The answer is D
Step-by-step explanation:
Answer:
The answer to this is False, False, True.
Step-by-step explanation:
A is false because WAU is an obstute angle, which can't be 55 degree.
B is flase because YAU is actually the angle that is 55 degree, not 35 degree.
C is true because WAX is congruent to YAU and it is 55 degree.
