for example if you have 3x^2+2x-1 then a=3 b=2 and c=-1 you plug those into the formula and solve to get the formula just look it up and go to images

Subtraction: -11
Answer=-11
Answer:
price of pencil is 0.74 and eraser is 0.72$
Step-by-step explanation:
Let, "p" represent pencils
and "e" represents erasers.
hence, according to question
13p+10e=16.75 ________(1)
and 25p+2e=19.85________(2)
Multiplying equation (2) by 5,
hence, 125p+10e=99.25________(3)
Substracting equation (3) and (1)
125p+10e-(13p+10e)=99.25-16.75
hence, 112p=82.5
p=0.74
substituting the value in equation (1),
13(0.74)+10e=16.75
9.57+10e=16.75
on solving,
e=0.72
hence, price of one pencil is 0.75$, and price of one eraser is $0.72
Yea is it the same value place
Answer:
3(7 + 4)2 − 24 ÷ 6 = 62
Step-by-step explanation:
3(7 + 4)2 − 24 ÷ 6 is the given expression.
Now, by the rule of BODMAS, where B = Bracket, O= of, D = divide,
M = multiplication, A = addition and S = subtraction
we try and solve the following expression in the same order.
Solving the bracket first, we get
3<u>(7 + 4)</u>2 − 24 ÷ 6 = 3(<u>11</u>)2 − 24 ÷ 6 =<u> 66</u> − 24 ÷ 6
Next, we solve divide,
66 − <u>24 ÷ 6</u> = 66 - <u>4</u>
Next, solving the subtraction, 66 - 4 = 62
Hence, 3(7 + 4)2 − 24 ÷ 6 = 62
