Answer:
4a + 4b - 2
Step-by-step explanation:
To evaluate h(a + b) , substitute x = a + b into h(x), that is
h(a + b) = 4(a + b) - 2 = 4a + 4b - 2
Answer:
X=140
Step-by-step explanation:
<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>
<em>The attachment you are showing us shows that we already know two angles</em>
<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>
<em />
X+70+60+90=360
X=360-70-60-90
X=140
4/5=87+2(55:10)-33 so that will be your answer if you simplify it
The first person who calculated pi was <span>Archimedes got really close however with the mathematics he had in his time he did not have decimal points nor could he use the number 0. So it has to latter once people recognize 0 as a number and the decimal point that we get what we have today. </span><span />
Hello,
sin x=1/2
==>x=π/6+2kπ or x=5π/6+2kπ
