Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis
= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms
= 3x³ + 23x² + 63x + 55
Answer:
Option 1
Step-by-step explanation:
-5/8, -1⅔, 0.8, ½
-5/8 = -0.625
-1⅔ is approximately -1.67
0.8
½ = 0.5
-1.67, -0.625, 0.5, 0.8
-1⅔, -⅝, ½, 0.8
Answer:
Step-by-step explanation:
Plug×=0 into the equation and solve for y.
X=number of girls.
y=number of boys.
We can suggest this system of equations:
2/7 x=3/5 y ⇒10x=21y ⇒x=21/10 y
y=x-165
We can solve this problem by substitution method:
x=(21/10)(x-165)
10x=21x-3465
10x-21x=-3465
-11x=-3465
x=-3465 /-11=315
y=x-165=315-165=150
Number of children=number of girls + number of boys
Number of children=315 +150=465
Answer: there were 465 children at the festival.
