Answer:
B - <em>∠b and ∠f</em>
Step-by-step explanation:
Corresponding angles are the angles in matching corners of the intersections in the traversal. Since <em>∠b</em> and <em>∠f</em> are in the same position relative to the intersection, they are corresponding.
The answer would be, "3(5x+2)"
Answer:
7+x=9
Step-by-step explanation:
if you subtract 7 from both sides of this you will get x=2 so the pen is $2
The general formula for the sides of right triangle is
a² + b² = c²
Subtitute the equation of a and b to the formula a² + b², evaluate if the answer will be the same as the equation of c²
a² + b²
= (m² - n²)² + (2mn)²
= (m² - n²)(m² - n²) + (2mn)(2mn)
= (m⁴ - 2m²n² + n⁴) + 4m²n²
= m⁴ + 2m²n² + n⁴
Factorize the result
m⁴ + 2m²n² + n⁴
= (m² + n²)(m² + n²)
= (m² + n²)²
= c²
It's proven by the formula that c² = (m² + n²)²
so the c will be m² + n²
So first you need to add 4 to each side to get (x+5)^2=16. Next you need to take the square root of each side to get √(x+5)^2=+-√16. After that simplify to get x+5=+-4. Now subtract 5from both sides to look like x=-5+-4. Now just do x=-5+4 and x=-5-4 then solve to get x=-1 and x=-9.
