The Answer Is 3a^2 3b^2 3c^2

Since all the variables equal each other, you may pick one variable to copy in the equation.

{a}^{2}  + a^{2}  + {a}^{2}  = 3 {a}^{2}

And since they're the same numbers, squaring a will have no effect in the equation.

Answer:

-\frac{15}{16}

Step-by-step explanation:

\frac{1}{4} ^{2}= \frac{1}{16}

2*(pq)= 2(\frac{1}{6})= \frac{1}{3}

-3q^{2}= -3(\frac{4}{9} )= -\frac{4}{3}

\frac{1}{16} +\frac{1}{3}-\frac{4}{3}=

\frac{1}{16} -1=

-\frac{15}{16}

Solve the following by elimination method <br> 11x+15y+23=0 and 7x-2y-20=0
mr Goodwill [35]
Let 11x + 15y + 23 = 0 be equation (1)
And 7x - 2y - 20 = 0 be equation (2)

Multiply equation (1) by 2:
22x + 30y + 46 = 0

Multiply equation (2) by 15:
105x - 30y - 300 = 0

Add equations (1) and (2):
22x + 105x + 30y - 30y + 46 - 300 = 0
127x - 254 = 0
127x = 254
x = 254/127
[x = 2]

Substitute x = 2 in equation (1) to find y:
11(2) + 15y + 23 = 0
22 + 15y + 23 = 0
15y + 45 = 0
15y = -45
y = -45/15
y = -3

Therefore, x = 2 and y = -3.

What is the slope of a line that is parallel to the line y = 3/4 + 2?
Elodia [21]
3/4 because it’s parallel so it has the same slope. It just doesn’t pass through the same line.
