(5x+4)(x+7) = (5x × x) + (5x × 7) + (4 × x) + (4 × 7)=
= 5x^2 +35x + 4x + 28 = 5x^2+39x+28
Answer:
a = -1 , b = 4 , c = 3 , d = 1
Step-by-step explanation:
Given:

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z
Comparing the right hand side with the left hand side
∴ a = -1
∴ b = 4
∴ c = 3
∴ d = 1

THE ANSWER IS THE SECOND ONE!
Answer:
Correct option: First one -> Hexagonal prism
Step-by-step explanation:
In the figure we have two hexagons and six rectangles. If we fold each part correctly, we can use the two hexagons as horizontal bases of a prism, and the six rectangles would be the sides of the prism (each rectangle connected to one side of lower hexagon and one side of upper hexagon).
So the figure created would be a hexagonal prism.
Correct option: First one.
