Answer:
66.63
Step-by-step explanation:
To find the diagonal length, use Pythagorean’s theorem.
Diagonal = √45^2 + 45^2 = √2025+2025 = √4050 = 63.63.
Hope this helps
Answer:
4(2x+3)
Step-by-step explanation:
8x+12
4(2x+3)
----------------
Note that 8x+12=4(2x+3),
because we factored out 4.
Sal's answer is wrong because even though 2(4x+6)=8x+12,
but the answer 4(2x+3) is more reasonable,
because our goal is to find the largest number when factoring an expression.
The equation: 6s - 10 = s
Add 10 to each side: 6s = s + 10
Subtract 's' from each side: 5s = 10
Divide each side by 5 : s = 2
Let:
P - perimeter
l - length
w - width
We know:
P = 118 m
l = 2w - 7
<h3>Rectangle perimeter's formula: P = 2l + 2w</h3>
We replace the length with 2w - 7.
P = 2×(2w - 7) + 2w
118 = 4w - 14 + 2w
118 = 6w - 14
6w = 118 + 14
6w = 132
w = 22 meters
It would help if you'd please use parentheses to indicate clearly what is to be multiplied or divided by what.
I am assuming (not claiming that I know) you meant:
(12f-16) (5)
------------ divided by --------------
16 9f^2 - 16
Factor as much as possible before attempting division:
4(3f-4) 5
--------- divided by -----------------
16 (3f-4)(3f+4)
This is equivalent to multiplying as follows:
4(3f-4) (3f-4)(3f+4)
---------- * -----------------
16 5
Is this what you meant? If so, please finish the work. If not, please copy down the original problem making liberal use of parentheses for clarity.
