So you can multiply $61.70 x 4 and there for your answer is $246.80
Answer:
93.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 93.5

Answer:
C
Step-by-step explanation:
y= x² - 3x - 3 → ( in standard form )
factor the quadratic to obtain intercept form
the factors of - 3 which sum to - 2 are - 3 and + 1
y = (x - 3)(x + 1) → ( in intercept form )
for vertex form use ' completing the square '
y = x² + 2( -1 )x + ( - 1 )² - ( - 1 )² = ( x - 1 )² - 4
y = ( x - 1 )² - 4 → ( in vertex form )
