Hi!
The answer should be third option.








Explanation: <u><em>First you had to subtract by the 20 from both sides. Then simplify it gave us 4j ≥ 2j+20. You can also subtract by the 2j from both sides. Then simplify its going to be 2j≥20. Next, you can also divide by 2 from both sides, and it gave us the answer is j≥10 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie</em></u>
Answer:
5 cm
Step-by-step explanation:
We know these are similar triangles, so we can use ratios of side lengths
x/40 = 4/32
Using cross products
32x = 4*40
32x = 160
Divide each side by 32
32x/32 = 160/32
x =5
I got the same question and Im pretty sure its d. 20
1st use the Step! Please, Excuse, My, Dear, Aunt, Sally! Ehich also means (PEMDAS) Parenthesis (), Exponents ", Multiple ×, Division÷, Addition+, and Subtraction-. Than your going to solve! (3n+5)×9=n×7
27n+45=7n
27n-7n=-45
20n=-45
n=-45/20= -9/4
