Answer:

9

Step-by-step explanation:

x^{2}  - 36 = 5x

x^{2} - 36 = 5x

x^{2} -5x = 36

9^{2} - 45 = 36

  + 45  + 45

-----------------------

81 = 81 ✅

9^{2} - 36 = 5(9)

81 - 36 = 45 ✅

Find the function value of cos^2 (7pi/8)
Dima020 [189]
Mhm, absolutely. Notice that we do not have a common unit circle value for any division of 8. But we do have a value for is 7pi/4. Now in order to actually get the value of 7pi/8, we use a half angle formula. So what we do is we will write out the formula and plug 7pi/4 into that formula, this will give us the value of 7pi/8. So the formula we need to plug 7pi/4 into is this: <span>±<span><span><span>1+cos2θ</span>2</span><span>−−−−−−−−−</span>√</span></span><span>SO if you plug in 7pi/4 for theta in that formula, you think you could simplify it to find 7pi/8?</span>

Perform the multiplication, (7x2+a2)(x2–3a2)
aksik [14]

Answer:

The given multiplied expression is

(7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4

Step-by-step explanation:

Given expression is (7x^2+a^2)(x^2-3a^2)

To find the multiplication of the given expression :

(7x^2+a^2)(x^2-3a^2)

By using the distributive property to solve the given expression as below

(7x^2+a^2)(x^2-3a^2)=(7x^2)(x^2)+(7x^2)(-3a^2)+(a^2)(x^2)+(a^2)(-3a^2)

=7x^2.x^2-21x^2a^2+a^2x^2-3a^2.a^2

=7x^{2+2}-21x^2a^2+a^2x^2-3a^{2+2}  ( by using the property a^m.a^n=a^{m+n} )

=7x^4-21x^2a^2+a^2x^2-3a^4

Adding the like terms in the above expression we get

=7x^4-20x^2a^2-3a^4

Therefore (7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4

Therefore the given multiplied expression is

(7x^2+a^2)(x^2-3a^2)=7x^4-20x^2a^2-3a^4
