WARRIOR [948]4 years ago
6 0

Answer:

A. 7.5 cm

Step-by-step explanation:

3/4 = (x + 3)/(2x + 1)

3(2x + 1) = 4(x + 3)

6x + 3 = 4x + 12

2x = 9

x = 4.5

BC = x + 3

= 4.5 + 3

= 7.5 cm

A student is using the elimination method to solve the system of equations below. What is the best first
vlada-n [284]

Answer:

The best first step would be to multiply the second equation by -2

Step-by-step explanation:

The best first step would be to multiply the second equation by -2

then you would have the following

\ \ \ \ \ \  4x - 5y = 2 \\-2*(2x)+ (-2)*y = (-2)*3

and when you multiply it is easy to eliminate because you will get

   4x - 5y = 2 \\-4x -2y = 6

and if you sum the equations you get

-7y = 8

so that is a single variable equation which is easier to solve.

What is the volume of the square pyramid with base edges 18 m and slant height 15 m?
stiv31 [10]

Answer: First option

Step-by-step explanation:

1. You must apply the following formula for calculate the volume of a square pyramid:

V=\frac{b^{2}*h}{3}

Where h is the height and b is a side of the base.

2. Calculate the height by applying the Pythagorean Theorem:

h=\sqrt{(15m)^{2}-(\frac{18m}{2} )^{2}}=12m

3. Therefore, the volume is:

V=\frac{(18m)^{2}*12m}{3}=1296m^{3}
