Answer:
Step-by-step explanation:
The solution for a system of equations when expressed graphically is coordinate of the point where the two graphs intersect.
Area = ab Sin O
= (63)(76) Sin 63 degrees
= 4266 square cm.
<u /><u />5.28 dollars per pound multiplied by 3.25 pounds is a total of 3.25*5.28=$17.16.
X(x+1) 1(x+4)
x^2+x+x+4
x^2+2x+4
2) Larger triangle is twice as large as the smaller one so x is 16
3) 16/12.8= 1.25 (This is the scale factor)
for y: 10/1.25=8
for x: 30/1.25=16
4) 8/6.4=1.25 (Scale factor)
for y: 14/1.25=11.2
for x: 15/1.25= 12
5) 22.5/9= 2.5 (scale factor)
for x: 12x2.5=30
for y: 35/2.5= 14
6) No because the scale factor is 2 but 14/8 does not equal to 2
