Answer:
the answer is x = 7
Step-by-step explanation:
1) replace the x with 7
2) 7 + 16 = 23
3) 4(7) = 28
4) 28 - 5 = 23
they're both equal as perpendicular angles should be!
Answer: Should be rational

Answer:
Option B, Area of pentagon = 58.5 Square feet
Step-by-step explanation:
The remaining part of the question is attached as image
Solution
Area of pentagon has a triangle and a trapezoid
Area of triangle = 0.5 *base *height = 0.5*9 *3 = 13.5 square feet
Area of trapezoid = Area of rectangle – 2* area of smaller triangles
= 9 ft * 6ft – ( 2 * 0.5 * 6 ft * (9 ft – 6ft) /2
= 54 – (1*6*1.5)
Area of pentagon = 13.5 + 45 = 58.5 Square feet
Hence, option B is correct
Answer:
center=(-7,5)
Step-by-step explanation:
The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).
you can find center by making equal to zero each term, then:
x+7 = 0
x=-7
y-5 = 0
y=5
then the center is (-7,5).
