Answer:
351 carrots
Step-by-step explanation:
13 = 1 tens + 3 units
27 = 2 tens + 7 units
<h3>13 × 27</h3>
13 × 27 = 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27 + 27
13 × 27 = 351
Conclusion:
Total Carrots is 351 carrots.
If the 26 bricks are each 7 cm, seems like multiplication or repeated addition would solve the problem. Multiplication would be faster. 26 x 7 = 182
182 cm tall.

Answer:
(c) P(x) = x^4 +3x^3 -10x^2 -30x
Step-by-step explanation:
If the polynomial has integer coefficients, its complex or radical roots come in conjugate pairs. That is, -√10 is also a root. The four roots mean the polynomial has degree 4. That eliminates all but answer choice C.
Each root 'a' gives rise to a factor (x -a), so the factored polynomial is ...
P(x) = (x -0)(x -(-3))(x -√10)(x -(-√10))
P(x) = x(x +3)(x² -10) = x(x³ +3x² -10x -10)
P(x) = x^4 +3x^3 -10x^2 -10x
Percent formula : is/of = %/100
is = 12
of = 60
% = x
now we sub
12/60 = x/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20
check..
0.20(60) = 12
12 = 12 (correct)
so 20% of 60 is 12
