Answer:
Yes they ate Equivalent
Step-by-step explanation:
Given the expression
h(x) = - 3x – 1;j(x) = – 7x + 11 ; k(x) = 21.22 – 262 – 11
H(x)•j(x) = (-3x-1)(-7x+11)
H(x)•j(x) = (-3x)(-7x)-3x(11)-1(-7x)(-1)(11)
H(x)•j(x) = 21x²-33x+7x-11
H(x)•j(x) = 21x²-26x-11
This shows that H(x)•j(x) = k(x)
Answer:
45°
Step-by-step explanation:
<em>complem</em><em>entary</em><em> </em><em>angl</em><em>es</em><em> </em><em>add</em><em> </em><em>up</em><em> </em><em>to</em><em> </em><em>9</em><em>0</em><em>°</em><em> </em><em>so</em><em> </em><em>it's </em><em>9</em><em>0</em><em>-</em><em>4</em><em>5</em>
15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
