The perimeter of an equilateral triangle is 6 cm more than the perimeter of a square. The length of a side of the square is 3 cm

yan [13]

3t=4s+5 (s=side of square, t= side of triangle)

s=t-3, t=s+3, using this value for t in the first equation gives us:

3(s+3)=4s+5

3s+9=4s+5

-s=-4

s=4

so the side length of the square is 4cm and the area of a square is just s^2

A=16cm^2

Consider the function f(x) = x2 + 2x – 35. If one of the zeros of the

Whitepunk [10]

If one zeros is x= -7 then the other zero is x=5

Step-by-step explanation:

We are given the function: $f(x) = x^2 + 2x-35$

If one zeros of the function is x=-7 we need to find other zero of the function.

We can find zeros of the quadratic equation by factorizing the equation

$f(x) = x^2 + 2x-35$

Factorizing the quadratic equation:

$x^2 + 2x-35=0\\x^2-5x+7x-35=0\\x(x-5)+7(x-5)=0\\(x+7)(x-5)=0\\x+7=0\,\,and\,\,x-5=0\\x=-7\,\,and\,\,x=5$

So, if one zeros is x= -7 then the other zero is x=5

First, multiply 1,127 & 1 by 2
1127 x 2 = 2254
1 x 2 = 2

so that’s 2,254 cups & 2 fl. ounces
since 8 fl. oz. make a cup, and we only have 2, the answer stays as it is

2,254 cups & 2 fl. ounces
