In a right triangle, 40-x=(3x). What is the value of x?

Mathematics
1 answer:
Archy [21]2 years ago
8 0

Answer:

x=10

Step-by-step explanation:

Let's solve your equation step-by-step.

40−x=3x

Step 1: Simplify both sides of the equation.

40−x=3x

40+−x=3x

−x+40=3x

Step 2: Subtract 3x from both sides.

−x+40−3x=3x−3x

−4x+40=0

Step 3: Subtract 40 from both sides.

−4x+40−40=0−40

−4x=−40

Step 4: Divide both sides by -4.

−4x

−4

=

−40

−4

x=10

The dimensions of a closed rectangular box are measured as 90 centimeters, 50centimeters, and 90 centimeters, respectively, with
gogolik [260]

Answer:

184 cm²

Step-by-step explanation:

Surface area of the rectangular box is expressed as S = 2(LW+LH+WH)

L is the length of the box = 90 cm

W is the width of the box = 50 cm

H is the height of the box= 90 cm

If there are error of at most 0.2 cm in each measurement, then the total surface area using differential estimate will be expressed as shown;

S = 2{(LdW+WdL) + (LdH+HdL) + (WdH+HdW)

Note that dL = dW = dH = 0.2 cm

Substituting the given values into the formula to estimate the maximum error in calculating the surface area of the box

S = 2{(90(0.2)+50(0.2)) + (90(0.2)+90(0.2)) + (50(0.2)+90(0.2))

S = 2{18+10+18+18+10+18}

S = 2(92)

S = 184 cm²

Hence, the maximum error in calculating the surface area of the box is 184cm²
