Answer:
The denominator of the fraction is 2x and the answer is a= -
Step-by-step explanation:
Suppose we have a quadratic equation of the form:
ax²+bx+c
The axis of symmetry of the parabola is given by:
From here, we must clear the value of a.
For this, we follow the following steps:
1) Pass 2a multiplying to the other side of the equation:
2ax=-b
2) Clear the value of a by passing 2x to divide:
Answer: 56 = 50 + 6
Explanation:
You can break apart a factor of a multiplication problem to help compute the product.
After braking apart the multiple digit factor into their ones, tens, hundreds, ... you can multiply the other factor by each part of the broken factor and then add the separate products to find the total product.
Let's do an expample with the given number, 56.
Being 56 a two-digit number you can break it up by tens and ones. In this way, 56 becomes 5 tens and 6 ones, i.e. 50 + 6.
Then you can multiply the other factor times 50 + 6 and get the product.
Let's say the other factor is 7, i.e. you want to find the product 7 × 56.
Therefore, 56 = 50 + 6 and 7 × 56 = 7 × 50 + 7 × 6
7 × 50 = 350
7 × 6 = 42
-------------------------
350 + 42 = 392
As you see, after braking apart the two digit factor 56 as per the place values of the digits, 50 and 6, you can find the product by adding the two separate products: 350 + 42 = 392.
Ummm i think it’s c i’m sorry if it’s not
Answer:
The answer is A 5(5x-2y)
Step-by-step explanation:
5(5x-2y)= 25x-10y
5x5=25 2x5=10
