Answer:

(7u+1)(2u-5)

Step-by-step explanation:

miltiply the coefficient of u² and the integer -5 = -70

from basic intuition: factors are -35 and +2

(which when added gives -33 and multiplies to give 70)

14u² -35u +2u -5

7u(2u-5) +1(2u-5)

(7u+1)(2u-5)

Match the formula to the correct figure.
forsale [732]

Given:

The figures cylinder, cube, cone, and pyramid.

To find:

The formula of volume for the given figures.

Solution:

Volume of a cylinder is:

V_1=\pi r^2h

Where r is the radius and h is the height.

Volume of a cube is:

V_2=a^3

Where a is side length of cube.

It is also written as:

V_2=l\times w\times h

Where l is length, w is width, h is height and l=w=h.

Volume of a cone is:

V_3=\dfrac{1}{3}\pi r^2h

Where r is the radius and h is the height.

Volume of a pyramid is:

V_4=\dfrac{1}{3}Bh

Where B is the base area and h is the height.

Therefore the table of formulae is shown below:

Figure                       Volume formula

Cylinder                   \pi r^2h

Cube                        l\times w\times h

Cone                        \dfrac{1}{3}\pi r^2h

Pyramid                    \dfrac{1}{3}Bh

PLEASE HELP ME I STINK AT THIS
Crank
The answer would be A. because 30 is how many she did but then h is the variable we are trying to figure out like the h can be any letter it just is there to show that the "person" does not know what the number is. Hope this helped!
