Answer:
I think that the answer is 24
Answer:
26in^2
Step-by-step explanation:
5 time 4 is 20in^2. plus 2 times 3 is 6in^2.
add 20 and 6 then you get 26in^2.
Answer:
21
Step-by-step explanation:
21+-23= -2
so the answer is "21"
Answer:
ZB = 54
Step-by-step explanation:
Complementary angles add to 90 degrees
ZA + ZB = 90
x-15 + x+3 = 90
Combine like terms
2x-12 =90
Add 12 to each side
2x-12+12 = 90+12
2x = 102
Divide by 2
2x/2 = 102/2
x = 51
We want to find the measure of ZB
ZB = x+3
ZB = 51+3
ZB = 54
In math, an extraneous solution is a solution of an equation that is obtained from solving the problem however this solution is not a valid solution. For instance,
<span><span>(1/(x − 2)) </span>+ (<span>1/(x + 2)) </span>= <span>4 / <span><span>(x − 2)</span><span>(x + 2)
</span></span></span></span><span><span><span><span>[(x − 2)</span><span>(x + 2)/</span></span><span>(x − 2)] </span></span>+ [<span><span><span>(x − 2)</span><span>(x + 2)/</span></span><span>(x + 2)] </span></span>= [<span><span>4<span>(x − 2)</span><span>(x + 2)] / [</span></span><span><span>(x − 2)</span><span>(x + 2)]
</span></span></span></span><span><span>(<span>x−2</span>)</span>+<span>(<span>x+2</span>)</span>=<span>4
x = 2
But <span>2</span><span> is excluded from the domain of the original equation because it would make the </span>denominator<span> of one zero and this is not valid.</span>
