Answer: x^2 + 19
Step-by-step explanation: Cancel out x^2 and add 7 and 12 together. 7 + 12 = 19. Next plug in x^2. So, its now x^2 + 19.
Hope this help!
Answer:
Same as Angle B. 90 degrees.
Step-by-step explanation:
If triangles are similar then they have the exact same angle measures. Angle m will have the same value as angle B. If angle B's measure is not found, then find it by adding angle A and angle C together and subtract from 180.
The picture is cut off but if A =60 and C=30 then 60+30=90 and 180-90=90. Angle B and M are both 90 degrees.
5 1/4 as a decimal is 5.25
this is because 1/4 is equal to 25/100
The answer is 5 planes - we count one for every side.
Hope this helped! Rate brainliest if you want. :)
Have a nice day!
