Answer:
area of the trapezoid=1/2(7+12)×5
=47.5cm
Answer:
C
Step-by-step explanation:
(a)
2 : 4 ( divide both values by 2)
= 1 : 2
3 : 6 ( divide both values by 3 )
= 1 : 2
Thus 2 : 4 = 3 : 6
(b)
3 : 9 ( divide both values by 3 )
= 1 : 3
Thus 1 : 3 = 3 : 9
(c)
4 : 6 ( divide both values by 2 )
= 2 : 3 ≠ 3 : 2
(d)
10 : 2 ( divide both values by 2 )
= 5 : 1
Thus 5 : 1 = 10 : 2
The calculation of the expression “four times as large as 124+645” end up in 1141.
<u>Step-by-step explanation:</u>
- The question is asked to Express the calculation “four times as large as 124+645”.
- The given statement can be written in the expression form to perform the calculations.
Here, the phrase 'four times' represents the multiplication of 4.
⇒ “four times as large as 124+645” = 4(124) + 645
So, the first step is to multiply 4 with 124.
⇒ 4 × 124
⇒ 496
The expression is now modified as “496+645"
We know that, the final result is the addition of the two numbers 496 and 645 which is calculated as
⇒ 496+645
⇒ 1141
Therefore, the calculation of the expression “four times as large as 124+645” end up in 1141.
When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:
(x + a) * (x - a) = x^2 - a^2
For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.
