Answer:
Step-by-step explanation:
<em>(17).</em> g(x) = x³ + 4x
f(x) = 4x + 1
( f × g )( x ) = ( x³ + 4x )( 4x + 1 ) = <em>4 </em>
<em> + x³ + 16x² + 4x</em>
<em>(19).</em> f(t) = 4t - 4
g(t) = t - 2
( 4f + 3g )( t ) = 4(4t - 4) + 3(t - 2) = 16t - 16 + 3t - 6 = <em>19t - 22</em>
<em>(21).</em> h(t) = t + 3
g(t) = 4t + 1
h(t - 2) + g(t - 2) = ( t - 2 ) + 3 + 4( t - 2 ) + 1 = t + 4t - 2 + 3 - 8 + 1 = <em>5t - 6</em>
Answer:
4L-12
Step-by-step explanation:
let's assume the length = L
then the width of the rectangle is L - 6
perimeter = 2× (a+b)
where "a" and "b" are the length and the width of the rectangle.
so perimeter = 2× (L + L - 6)
2 × ( 2L - 6)
4L - 12
Answer:
9x2 +42x + 24 <u>is</u> (x + 4) (9x + 6)
9x2 + 30x + 24 <u>is</u> (3x + 6) (3x + 4)
9x2 + 58x + 24 <u>is</u> (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)
Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
Answer:
14. -21 over 5, 1 over 4
Step-by-step explanation:
PQ: perform the slope formula: y2-y1 divided by x2-x1
-3 - 17 divided by 1 - (-4) = -21 divided by 5
RS: 4 - 3 divided by -5 - (-9) = 1 divided by 4
