Answer: answer is C
Step-by-step explanation:
for find x
(5x+30)+5x=90
5x+30+5x=90 add like terms
after,
10x+30=90
10x+30-30=90-30
10x/10=60/10
x = 6
to obtain answer as C
it mean
(5x+30)+5x=90
(5(6)+30)+5(6)=90 we know x=6 so add 6 to x and multiply and obtain answer is correct!
30+30+30=90
Answer:23 cm
Step-by-step explanation:
Because it would equal the same amount because there are 10 mm in a cm
Answer:
4x2−24x4x2-24x
Factor 4x4x out of 4x24x2.
4x(x)−24x4x(x)-24x
Factor 4x4x out of −24x-24x.
4x(x)+4x(−6)4x(x)+4x(-6)
Factor 4x4x out of 4x(x)+4x(−6)4x(x)+4x(-6).
4x(x−6)4x(x-6)
4x2−24x4x2-24x

Answer:
16 cm^2 and 49 cm^2
Step-by-step explanation:
The ratio of areas is the square of the ratio of linear dimensions, so is ...
(4/7)^2 = 16/49
The sum of these "ratio units" is 16 +49 = 65. The sum of triangle areas is 65 cm^2, so each "ratio unit" must stand for 1 cm^2 of area. That is, the triangles must have areas of ...
