Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,

Now, subtract 2 from the above expression,

Hence, the required expression is x²-2.
Answer:
Yes
Step-by-step explanation:
x , y
(-3 , 0)
plug in the numbers
2(-3) + 6(0) = -6
-6 = -6
Answer:
y = 12x
Step-by-step explanation:
The shirts sell for $12 each, so the income equation is
y = 12x
