Answer:
29x - 12
Step-by-step explanation:
Step 1: Use the distributive property
8(x-5) + 7(3x+4)
= 8x - 40 + 21x + 28
Step 2: Combine like terms
= 29x - 12
Sin θ =

If θ = 51° ; opp = QR ; hyp = 17 cm
Then sin 51° =

⇒ QR = (sin 51°) (17 cm)
= 13.21 cm
∴ the answer is OPTION C
Answer:
2587mm^3 approx!
Step-by-step explanation:
first you divide the nut into 6 part(in triangle now, by joining centre to each edge)
let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height
i.e, 1/2×13×15=97.5(mm^2)
now when we consider depth of that traingular part,we will get volume of that part as area×depth
i.e, 97.5×6=585(mm^3)
now volume of all the 6 triangular part is 585×6=3510(in mm^3)
now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately
now reqired volume will be volume of that hexagonal part minus that of circular cavity
=3510-923
=2587mm^3
