Help please not sure on the answer :)

60

Step-by-step explanation:

5(a + 2) + 6(2a - 3)

Expand the brackets.

5a + 10 + 12a - 18

Add or subtract like terms.

17a - 8

Plug a = 4 and evaluate.

17(4) - 8

68 - 8

= 60

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
