Answer:
B. 12
Step-by-step explanation:
✔️Find the value of x
The side lengths of two similar triangles are always proportional.
Given that ∆ABC ~ ∆LMN, therefore:
AB = 5
LM = 10
AC = x + 5
LN = 3x + 3
Plug in the values
Cross multiply
(distributive property)
Collect like terms
Divide both sides by 5
x = 7
✔️Find AC
AC = x + 5
Plug in the value of x
AC = 7 + 5
AC = 12
Answer:
40
Step-by-step explanation:
plug -8 into the x so
f(-8)=(-8)^2-3(8)=
=64-24=
=40
therefore, f(-8)=40
Answer:
B:25°
Step-by-step explanation:
Now 
gets bisected by 
.
Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is 
so the other angle has to be also.
Hence, the 
.
Answser: the image of D will be the same drawing (D), translated to the right of the line m.
Explanation:
1) The first reflection, accross the line l, will be the letter<span> D turned (with the "belly" to the left instead of the right), located to the right of the line l and to the left of the line m.
2) The second reflection, accross the line m, will turn the letter again leting it equal to the original picture, now translated to the right on the line m.
