Answer:
7) C
8) B
9) C
Step-by-step explanation:
7) sqrt[(8-8)² + (-5-7)²] = 12 units
8) y = 4x
9) y = 6 - x
Answer:
9 jars
Step-by-step explanation:
If 3 jars cost $2
and 3 times 2 is $6 then just multiply 3 by 3 to get 9 jars.
Hope this helped.
A brainliest is always appreciated.
Since this is a triangle all the angles within the triangle add up to 180 degrees so....
82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees
Answer:
1/8^4
Step-by-step explanation:
when divinding exponents with the same base, subtract the power. you get 8^-4. since the problem specifies no negative exponents you need to simplify. this give you 1/8^4
