You would subtract 4a from both sides to get 7a + 9 = 30. Then you should subtract 9 from both sides to get 7a = 21. Then divide both sides by 7. Final answer: a=3
Answer:
B no
Step-by-step explanation:
If (n - 10) is a factor then if the polynomial equals zero when evaluated for 10 it is a factor
10³ - 17(10)² + 61(10) + 92
= 1000 - 1700 + 610 + 92
= 2 ≠ 0
Then ( n - 10) is not a factor of the polynomial
I like the cat on your pfp LOL sorry i couldn’t help tho
Answer: 14.8units²
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
Answer:
x = 30°
Step-by-step explanation:
5x + x + x + 5x = 360° ( exterior angle property)
12x = 360°
x = 360/12
x = 30°
