Well if X is < (greater than) -7 it must be 0 because if -15, -10, -7, -7.2, are all less than -7 then 0 is the best answer
Answer:
A, C, D
Step-by-step explanation:
Consider triangles NKL and NML. These triangles are right triangles, because
In these right triangles:
- - reflexive property;
- - given
Thus, triangles NKL and NML by HA postulate. Congruent triangles have congruent corresponding parts, so
Since
then
Option B is false, because KN=52 units.
Option E is false, because LN is congruent KN, not LM
Start by distributing through the parentheses on
each side of the equation to get 3x - 12 = 2x - 12.
Now move your x's to the left by subtracting
2x from both sides to get x - 12 = - 12.
Now move your numbers to the right by
adding 12 to both sides to get x = 0.
So, the solution to this equation is <em>x = 0</em>.
Answer:
(a)
--- the catboat
--- the sloop
(b)
-- the catboat
--- the sloop
Step-by-step explanation:
Incomplete question (See attachment)
For the catboat, we have:
For the Sloop, we have:
Solving (a): The area of both sailboats.
Since both are triangular, we use:
For the catboat
For the sloop
<em>The catboat has the greater sail area because 27 > 25</em>
Solving (b): Cost of sail for each.
We have the unit price to be:
So, the cost is calculated by multiplying the unit price by the total area.
So, we have:
For the catboat;
For the sloop
