A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x
∠B = 38° + x
∠A and ∠B are complementary
If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13
Answer:
54 square meters
Step-by-step explanation:
Similar figures have corresponding lengths as equal ratios.
Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is 
<em>this means the lengths of larger is 1.5 times lengths of smaller.</em>
<em />
In terms of area, the scale factor is squared. Hence the scale factor for area is 
<em>this means the area of larger is 2.25 times the area of smaller.</em>
<em />
Now, Let area of smaller trapezoid be x so we can say: 
<em>to nearest square meter, </em><em>x = 54 meters squared</em>
How many times a particular number is a zero<span> for a given polynomial. For example, in the polynomial function f(x)=(x–3)4(x–5)(x–8)2, the </span>zero<span> 3 has </span>multiplicity<span> 4, 5 has </span>multiplicity<span> 1, and 8 has </span>multiplicity<span> 2. Although this polynomial has only three </span>zeros<span>, we say that it has seven </span>zeros<span> counting </span><span>multiplicity</span>
You have to plug in 0 to each variable and solve to get each axis intercepts giving you. (0,-3) (6/5,0)
I dont really know how to explain it so i just solved it (the answer is boxed) but i hope this helps !
