Área= Lw (length * width)
Perimeter= 2l + 2w
Área- 5(8x +3)
Simplify- 40x +15
Perimeter- 2(8x+3) + 2(5)
Simplify- 16x+6+10
Simplify more- 16x +16
M=c/at
Divide both sides by a and t to isolate m. Then the solution is just m=c/at
Answer:
5,4
Step-by-step explanation:
here is the rule (4,-5) rotate 90 clockwise = (5,4)
4,-5 will put you in the 4 quadrant rotate it 90 clock wise Put you in the first quadrant
Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2
