Step-by-step explanation:
Here Given
Total counters = 81
red counters are 9 more than the yellow ones.
And Yellow counter = blue counter
So let the Yellow counter be x and as blue counter and yellow counter are same then blue counter will be also x
And by the question
Red counter = 9 + x
Now
9 + x + x + x = 81
9 + 3x = 81
3x = 81 - 9
3x = 72
x = 72 / 3
Therefore x = 24
Now
Red counters = 9 + 24 = 33
Blue counters = 24
Yellow counters = 24
Hope it helped :)
Answer:
850 m²
Step-by-step explanation:
There are 3 different pairs of rectangles—the side rectangles, the rectangles on the top and bottom, and the other side rectangles.
10x11=110
110x2=220
15x10=150
150x2=300
15x11=165
165x2=330
330+300+220=850 m².
Hello!
Explanation:
Distributive property: a(b+c)=ab+ac
Multiply by the numbers.
Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.
First, apply used their FOIL.
Foil: (a+b)(c+d)=ac+ad+bc+bd
2x*7x+2x(-6z)+5z*7x+5z(-6z)
Then you can also apply by the minus/plus sign.
2*7xx-2*6xz+5*7xz-5*6zz
And finally simplify by equation.
2*7xx-2*6xz+5*7xz-5*6zz
<em><u>Answer: =14x²+23xz-30z²</u></em>
Hope this helps!

The total area of the the picture and frame is given by the equation A = (16 + 2x)(24 + 2x) = 384 + 32x + 48x + 4x^2 = 4x^2 + 80x^2 + 384
