What is the answer to this question?

lions [1.4K]

*Hint: The formula to solve this is SA = 2bs + b^2

Now that you know the formula, plug in and solve.

SA = 2(5)(8) + (5)^2
SA = 80 + 25
SA = 105

Now that you see that the question is asking for the answer in yards, you convert feet into yards.

3 feet = 1 yard.

105 is divided by 3 and you get 35.

The answer is 35 square yards.

X+4(2+3) < 5x is there a solution??

zavuch27 [327]

Answer:

$\Huge\boxed{\mathsf{\longrightarrow X>5}}$

Step-by-step explanation:

Isolate x on one side of the equation.

First, do parenthesis.

4(2+3)

Add.

3+2=5

Multiply.

4*5=20

Rewrite the equation problem.

x+20<5x

Secondly, subtract 20 from both sides.

x+20-20<5x-20

Solve.

x<5x-20

Thirdly, subtract 5x from both sides.

x-5x<5x-20-5x

Solve.

5-1=4

-4x<-20

Then, multiply -1 from both sides.

(-4x)(-1)>(-20)(-1)

Solve.

(-4x)(-1)=4x

(-20)(-1)=20

4x>20

Divide by 4 from both sides.

4x/4>20/4

Solve.

20/4=5

x>5

$\Large\boxed{\mathsf{\Rightarrow X>5}}}$

The solutions is 5, therefore, the correct answer is x>5.

the difference between seven times one number and three times a second number is 25. The sum of twice the first and five times t

inysia [295]

$\left \{ {{7*x - 3*y=25} \atop {2*x + 5*y=95}} \right.$

$\left \{ {{7x - 3y=25}(I) \atop {2x + 5y=95}(II)} \right.$

$\left \{ {{7x - 3y=25}simplify*(5) \atop {2x + 5y=95}simplify*(3)} \right.$

$\left \{ {{35x - \diagup\!\!\!\! 15 y=125} \atop {6x + \diagup\!\!\!\! 15y=285}} \right.$

$\left \{ {{35x =125} \atop {6x =285}} \right.$

$41x = 410$

$\boxed{x=10}$

<span>Replace the value of "x" in the second equation (II) to find the value of "y", thus:
</span> $2x + 5y=95$
$2*(10)+5y = 95$
$20+5y=95$
$5y=95-20$
$5y=75$
$y = \frac{75}{5}$
$\boxed{y=15}$
