Answer:
320
Step-by-step explanation:
42^2-38^2= (42+38)(42-38)
=80*4
=320
Answer:
one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)
other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)
Step-by-step explanation:
ratio of the angles 6:5
when you draw diagonal inside a rhombus it creates four right angled triangle
one angle=90
6x+5x=90 ( the other angles is complimentary)
11x=90
x=90/11
one angle : 6x=6(90/11)=540/11 (49.1 rounded to the nearest tenth)
other angle=5(90/11)=450/11 (41 degrees rounded to the nearest ones)

Answer:
x = 6
Explanation:
y = x - 4
26 = 4x + y
If y = y, then we can rewrite this system as this: 4x + x - 4 = 26
Then we combine like terms and add 4 on both sides to give us 5 x = 30
. Divide by 5 on both sides and we arrive at the solution: x = 6
