Which expression is equivalent to x2+3x+ 3+ (2x+134+15) - (x+5))

tia_tia [17]

Answer:

$x^{2} + ( 4x) + (147)$

Step-by-step explanation:

Here, the given expression is

$x^{2} +3x +3 + (2x+134+15) - (x+5)$

Now, simplifying the brackets, we get

$x^{2} +3x +3 + (2x+134+15) - (x+5)$ = $x^{2} +3x +3 + 2x+134+15 - x -5$

Now, operate on the like terms.

= $x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)$

= $x^{2} + ( 4x) + (147)$

Hence, the given expression is simplified to the quadratic equation $x^{2} + ( 4x) + (147)$

Find the value of the variable in the parallelogram. RZ = 4x + 2 SW=9x - 8 X=

ipn [44]

Answer:

$x=12$

Step-by-step explanation:

This parallelogram contains a right angle. This tells us that the parallelogram is a rectangle.

The diagonals in a parralelogram bisect each other.

The diagonals in a rectangle are congruent.

$RZ+ZT=RT\\(4x+2)+(4x+2)=RT\\8x+4=RT$

$RT=SW\\8x+4=9x-8\\4=x-8\\x=12$

Water flows from the faucet at the rate of 5 L every 25 seconds at this rate how much water will flow from the faucet in 45 seco

Citrus2011 [14]

5L:25Seconds=1L:5seconds
In 50 seconds there will be 10L of water
In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out
10L-1L=9L
There will be 9L of water
