tom is 2 kg heavier than harry, who is 3 kg heavier than ben. when they add up all their weights, it comes to 65 kg. how many kg

lesya [120]

Answer:

Step-by-step explanation:

Let Harry = x

Tom = harry + 2

Tom = x + 2

Ben + 3 = harry

harry - 3 = ben

x - 3 = ben

Tom + harry + Ben = 65

x + 2 + x + x - 3 = 65

3x - 1 = 65 Add 1 to both sides

3x = 65 + 1

3x = 66 Divide by 3

x = 66/3

x = 22

So harry = 22 kg

What is :<br><br>(49^x)(7^x^2)=2401^2

ludmilkaskok [199]

$(49^x)(7 ^{x^2})=2401^2 \\ \\( (7^2)^x)(7 ^{x^2})= (7^4) ^2 \\ \\ 7 ^{2x}\cdot 7^{x^2}=7^{8} \\ \\ 7 ^{2x+x^2} =7^{8} \\ \\2x+x^2 =8$

$x^2-2x-8 = 0\\ \\ a=1, \ b=-2, \ c=-8 \\ \\\Delta =b^2-4ac = (-2)^2 -4\cdot1\cdot (-8) = 4 +32 =36 \\ \\x_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{2-\sqrt{36}}{2 }=\frac{ 2-6}{2}=\frac{-4}{2}=-2 \\ \\x_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{2+\sqrt{36}}{2 }=\frac{ 2+6}{2}=\frac{8}{2}= 4 \\ \\Answer: \ x=-2 \ \ or \ \ x=4$
