Answer:
The last statement is the true.
Step-by-step explanation:
As shown in the figure.
A'B' is the image of AB by dilation of factor x and the center of dilation is C
So, x =
So, according to the previous, the true statement is:
He is incorrect because the scale factor is One-third. CB is actually 2 + 4 = 6. CB is the pre-image, so the scale factor is StartFraction C prime B prime Over CB EndFraction = StartFraction 2 Over 6 EndFraction = one-third.
The formula for the area of a triangle is 1/2*b*h
The best thing to do is to multiply the answers then half them.
7*12= 84
84/2= 42
Therefore, the area is 42cm2
Hope this helps :)
Simplify 1/4x to x/4
-x/4 - 14y - 1/8x + 2y + 18
Simplify 1/8x to x/8
-x/4 - 14y - x/8 + 2y + 18
Collect like terms
(-x/4 - x/8) + (-14y + 2y) + 18
Simplify
-3/8x - 12y + 18
Answer:
pls follow me mark me as brainiest
52/8 is 48/8+4/8, or 6+4/8. Therefore, our answer is six, with remainder four.
