Answer:
24
Step-by-step explanation:
Plugin the value of x and y
8[x + y] = 8*[5 - 2]
= 8 *3
= 24
Answer:
Step-by-step explanation:
We want to for a polynomial function whose real zeros are -2 with multiplicity 2 and 4 with multiplicity 1.
If -2 is a zero of a polynomial, then by the factor theorem, x+2 is a factor.
Since -2 has multiplicity 2, (x+2)² is a factor.
Also 4 is a zero which means x-4 is a factor.
We write the polynomial in factored form as:
We expand to get:
We expand further to get:
The number of bars which can be cut for the 1" X 1" and 2" X 2" square bars are; 117 and 29 units respectively.
<h3>How many bars can be cut from the pan in each case?</h3>
The total area of the given pan can be evaluated as follows;
Area = length × width
= 9 × 13
= 117 square units.
Hence, the number of 1" X 1" bars can be cut which can be cut from the pan;
= 117/(1×1)
= 117 1" X 1" bars.
For the 2" X 2" square bars, we have;
= 117/(2×2);
29 remainder 1 square unit.
Ultimately, one square unit of the pan is wasted for the 2" X 2" square bars.

The expression that is equivalent to (-2)^4/(-2)^2 is (-2)^6/(-2)^4
<h3>How to determine the expression that is equivalent to (-2)^4/(-2)^2?</h3>
The expression is given as:
(-2)^4/(-2)^2
Apply the law of indices
(-2)^4/(-2)^2 = (-2)^(4 -2)
4 - 2 has the same value as 6 - 4
So, we have:
(-2)^4/(-2)^2 = (-2)^(6-4)
Apply the law of indices
(-2)^4/(-2)^2 = (-2)^6/(-2)^4
Hence, the expression that is equivalent to (-2)^4/(-2)^2 is (-2)^6/(-2)^4
