The solution for this question is simple. First we need to divide both numbers by 2 which will give us 10 and 7. This is the equation x^2/10^2 + y^2/7^2 = 1sqrt(100-49) = 7.14 (the answer do not have a perfect square root)
Foci are 14.28 units apart

Triangle abc is similar to triangle FGH solve for p plebs.

12345 [234]

The value of <em>p </em>is 21

Step-by-step explanation:

ΔABC ~ ΔFGH

$\frac{ab}{fg} = \frac{bc}{gh} \\ \frac{35}{p} = \frac{10}{6} \\ p = \frac{35 \times 6}{10} \\ p = \frac{210}{10} \\ p = 21 \\ \\ or \\ \\ \frac{ab}{fg} = \frac{ac}{fh} \\ \frac{35}{p} = \frac{30}{18} \\ p = \frac{35 \times 18}{30} \\ p = \frac{630}{30} \\ p = 21$

So, the value of <em>p</em> is 21

Answer:

Step-by-step explanation:

The rule with like bases is that when you multiply them you add their exponents.

$m^4*m^1=m^5$

Therefore, our final simplification is

$4m^5n^7$

Find a solution to the linear equation - 2x – 2y = 8 by filling in the boxes with a valid value of x and y.

adoni [48]

Answer:

$-2(-4)-2(0)=8$

Step-by-step explanation:

Given

$2x - 2y = 8$

Required

Gaps: -2( )-2( )=8

<em>Fill in in the gaps</em>

The are numerous solutions to this.

One of them is:

Assume y = 0.

So, we have:

$-2x - 2*0 = 8$

$-2x - 0 = 8$

$-2x = 8$

Divide through by -2

$\frac{-2x}{-2}= \frac{8}{-2}$

$x= -4$

Fill in the gaps with these values of x and y respectively:

Hence; one solution is: $-2(-4)-2(0)=8$
