Expression (non-algebraic): 3+2
An equation: 2x +1 = 21
An inequality: 2x > 2+2
Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°
Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + b (m is the slope and b is the y-intercept)
y = mx + 1
Equation for slope: 
(0,1) (1,-1)
=
= -2
y = -2x + 1
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1
You can check your work by multiplying 13.1 by 13.1 which equals 170.3
