Answer:
12 ft squared
Step-by-step explanation:
multiply 4 by 3 and that will get you to 12
Answer:
m<A = 35
m<B = 55
Step-by-step explanation:
Complementary angles mean the 2 angles add up to 90 so:
y - 16 + y + 4 = 90
2y - 12 = 90
2y = 102
y = 51
m<A:
y - 16
51 - 16
35
m<B:
y + 4
51 + 4
55
Answer:
70 standard boxes, 40 deluxe boxes
Step-by-step explanation:
standard: x
deluxe: y
x + y = 110
7x + 11y = 930
Multiply the first equation by 7 and subtract.
7x + 7y = 770
-(7x + 11y = 930)
You get -4y = -160
y = 40
Substitute y into the first equation.
x + 40 = 110
x = 70
Answer:Least common multiple (LCM) of 3 and 4 is 12. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 3 and 4 with GCF Formula.
Step-by-step explanation:
Equation with roots -10 and -8 is: y = a(x + 10)(x + 8) = a(x^2 + 18x + 80) = ax^2 + 18ax + 80a . . . . . . . . (1)
Equation with vertex at (-9, -3) is y = a(x + 9)^2 - 3 = a(x^2 + 18x + 81) - 3 = ax^2 + 18ax + 81a - 3 . . . . . . . . (2)
From (1) and (2), we have
80a = 81a - 3
a = 3
Therefore, required equation is:
y = 3x^2 + 18(3)x + 80(3) = 3x^2 + 54x + 240
