7(K+8) + 7*k +7*8 you must show where the number 7 has been placed with each addend individually .
1) Corresponding angles
2) Alternate angles
Log base 10 (1/1000)
10^x = 1/1000
Log1/1000 = -3
Answer:
Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm.
Hello!
You can solve this algrbraically
2/3 x = -20
Multiply both sides by 3
2x = -60
Divide both sides by 2
x = -30
The answer is B) -30
Hope this helps!
