Area of 3/4 circle = 3/4 x π x r²
= 3/4 x 22/7 x 6²
= 84.86cm²
That should be the correct answer
Hope this helps!!
ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
Answer:
y = 5x - 2 (0, 2) (1, 4) (2, 7) (3, 13)
Step-by-step explanation:
Answer:
3x^4-18x^3+27x^2-12x
Step-by-step explanation:
Multiply the second paréntesis for each term of the first parentage
3x^2×(x^2-2x+1)-12x×(x^2-2x+1)
Multiply parentage by 3x^2
3x^4-6x^3+3x^2-12x×(x^2-2x+1)
Multiply the parentage by -12x
3x^4-6x^3+3x^2-12x^3+24x^2-12x
Group similar terms
3x^4-18x^3+27x^2-12x
