Answer:
= a^7
Step-by-step explanation:
Given in the question,
a^5 * a^4 / a²
To find,
show working
<h3>Explanation</h3>
As we know that to divide exponents (or powers) with the same base, we subtract the exponents. Division is the opposite of multiplication, so when multiplying the exponents (or powers) with the same base add the exponents.
<h3>Working</h3>
a^5 * a^4 / a²
= a^(5 + 4) / a² (Multiplying)
= a^9 / a²
= a^(9 - 2) (Dividing)
= a^7
<em>hence shown</em>
Answer:
f(x)=4x^2 and g(x)=-8x^2 + 4x - 4
(f+g)(x) = -8x^2 + 4x - 4 + 4x^2 = -4x^2 + 4x - 4 = -4(x^2 -x + 1)
(f+g)(-3) = -4( -3^2 -(-3) + 1) = -4 x 13 = -52
Hope this helps!

It's a proportion. Set it up as 3/30 * x/11= 1.1
Answer:
The side lengths cannot belong to a right triangle.
Step-by-step explanation:
This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.
If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.
Hope this helps!
