Answer:
Mark has 18 shirts
Given that together they have 140 shirts.
x + 7x - 4 = 140
8x = 140 + 4
8x = 144
x = 144/8
x = 18
Joe has 122 shirts
7x - 4
7 × 18 - 4
126 - 4
= 122
5 · (6 - 1) + 3
= 5·5 + 3
= 25 + 3
= 28
Answer:
BC, CA, AB
Step-by-step explanation:
the measure of each angle is super important, bc you use it to compare the lengths of each side in this problem. the bigger the angle, the bigger the opposite side is. so, if you were to draw a line from the angle measuring 83 degrees, it would go to side AB. since the angle measure is the largest out of the three angles, it makes AB the largest side.
hopefully that makes sense!! :)
Answer:
1) f(g(2)) = 24
2) f(g(-1)) = -4
Step-by-step explanation:
1) GIven f(x) = x²+2x and g(x) = 2x
f(g(x)) = f(2x)
f(2x) = (2x)² + 2(2x)
f(2x) = 4x² + 4x
f(g(x)) = 4x² + 4x
f(g(2)) = 4(2)² + 4(2)
f(g(2)) = 16+8
f(g(2)) = 24
2) f(x) = x+1 and g(x) = 5x
f(g(x)) = f(5x)
f(5x)= 5x + 1
f(g(x)) = 5x + 1
f(g(-1)) = 5(-1) + 1
f(g(-1)) = -5+1
f(g(-1)) = -4
If two sides of one triangle are congruent to two sides of another triangle then CPCTC makes it SSS
