Answer:
Option B is correct.
The reflection rule is followed here is, 
.
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.
Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is,
Answer:
380
Step-by-step explanation:
You just have to substitute the variables for the number value.
(4x2 +3x4)x(2x3x4-5)
(8+ 12)x(24-5)
(20)x(19)
=380
Answer:
129
Step-by-step explanation:
for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do
180=x+19+4x+1
step 1 combine like terms
4x+x=5x
19+1=20
now we have
180=20+5x
step 2 subtract each side by 20
20-20 cancels out
180-20=160
now we have
160=5x
step 3 divide each side by 5
5/5 cancels out
160/5 = 32
x=32
now we want to plug in 32 for each expression to find which one is greater
(32)+19=51
4(32)=128
128+1=129
so the answer is 129
hope this helps :D
30x-12-8x+40
22x-12+40
22x +28
They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.
Hope this helps.
