Answer:
a.(3x+2)(5x+8)
Step-by-step explanation:
area of rectangle formula- length times width
so l= 3x+2 and w= 5x+8
Given that the two cone are similar, then
3/7 = x/5
7x = 15
x = 15/7
Answer:
Step-by-step explanation:
Given
Required
Graph the solution
Multiply both sides by 3
<em>See attachment for graph (Assume T is on the x-axis)</em>
51= 3k
divide both sides by 3
to get k by itself
51/3= 3k/3
cross out 3 and 3, divide by 3 and becomes k
k= 17
Answer: k= 17
