Answer:
The first one is c
Step-by-step explanation:
Answer:
(-3, -1)
Step-by-step explanation:
it starts at (3, 1)
its reflected over the y-axis giving you the points (-3, 1)
then it is reflected over the x-axis to give you the points (-3, -1)
Answer:
x=3cm
Step-by-step explanation:
We have three figures.A triangle(8 by X+3).In it we have another triangle(4 by x)and a trapesium
thus that means the area of the trapesium+area of small triangle=area of big triangle.
1)Area=1/2lengthxwidth. =1/2×8×(x+3)
=4(x+3)
=4x+12cm³
2)Area=1/2lengthxwidth. =1/2×4×x
=2x
3)area=1/2(a+b)h
=1/2(x+3+x)×4
=1/2×4(2x+3). (area of trapesium)
=2(2x+3)
=4x+6cm³
thus:
2x+4x+6=4x+12 put like terms together
2x+4x-4x=12-6
2x=6 divide both sides by 2
x=3cm
Answer:
Just subtract 47 from 68 and the answer is D.
Answer:
1x + 4 - 5x - 2 = -4x + 2
Step-by-step explanation:
1x + 4 - 5x - 2
combine like terms
(-5x + 1x) + (4 - 2)
-4x + 2
