Answer:
The choose B. x = 7 , x = – 15
(x+4)-5=6
x +4-5=6 —> x=6-4+5 —> x= 7
– (x+4)-5=6 —> -x -4-5=6—> x = -4 -5 -6 —> x = – 15
I hope I helped you^_^
Answer:
D
Step-by-step explanation:
the triangle has reflected across either x-axis or p-axis. If across x-axis, the triangle needs to translate left and then up (no option for this).
Answer:
19.25
Step-by-step explanation:
3a(4a^2 - 5a + 12)=12a^3-15a^2+36a (C)
Answer:
x: C
y: A
z:
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is larger than either of the legs by a factor of
. The length of x is therefore:

In a 30-60-90 triangle, the longer leg is larger than the shorter leg by a factor of
. Therefore:

The hypotenuse of the 30-60-90 triangle is twice larger than the smallest leg, so it has a length of
.
By the pythagorean theorem, you can find z+y:

Hope this helps!
