Answer:
Step-by-step explanation:
A cube has 6 faces so:
Area of 1 face = 486/6 = 81 cm^2.
Lateral area = 4 * face area
= 4 * 81
= 324 cm2.
Answer:
A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation:
An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.
Answer:
34
Step-by-step explanation:
4x+36=6x-2
x=19
m=112
p=112
so they are both congruent that means angle N and Q are congruent
180-112= 68
68 and they are two angles so
68 divide 2 and u get 34
Angle N is 34 and angle Q is 34 too
Xy^2 = 4,7^2 +6,5^2
xy^2 = 22,09 +42,25
xy = sqrt(64,34)
xy = 8,02
Answer:
C
Step-by-step explanation:
On a number line, larger numbers are toward the right, and smaller ones are toward the left.
They both are negative numbers, which means that <em>they are smaller than 0, therefore, they will both be on the left side</em>. The means A and C are not the right answers.
Because<em> -⁸/₁₈ is larger than -¹⁷/₂₇, it will be further right</em>, which makes C the correct answer.
