Answer:

a = 7

Step-by-step explanation:

3a + 4 = a + 18

Add -a and -4 on both sides.

3a - a = 18 - 4

2a = 14

Divide 2 into both sides.

a = 14/2

a = 7

The outside surfaces of a cereal box are printed with text and pictures. What is the print area (surface area) of a box that is
lyudmila [28]
Your answer would be 200^2in. 8*10 = 80. 80*2(because the box has an opposite side)= 160. Then 2*10 = 20. 20*2 (for the same reason)= 40. 160 + 40 = 200.

Factorise each of the following algebraic expressions completely,
LekaFEV [45]

Answer:

see explanation

Step-by-step explanation:

(a)

Given

2k - 6k² + 4k³ ← factor out 2k from each term

= 2k(1 - 3k + 2k²)

To factor the quadratic

Consider the factors of the product of the constant term ( 1) and the coefficient of the k² term (+ 2) which sum to give the coefficient of the k- term (- 3)

The factors are - 1 and - 2

Use these factors to split the k- term

1 - k - 2k + 2k² ( factor the first/second and third/fourth terms )

1(1 - k) - 2k(1 - k) ← factor out (1 - k) from each term

= (1 - k)(1 - 2k)

1 - 3k + 2k² = (1 - k)(1 - 2k) and

2k - 6k² + 4k³ = 2k(1 - k)(1 - 2k)

(b)

Given

2ax - 4ay + 3bx - 6by ( factor the first/second and third/fourth terms )

= 2a(x - 2y) + 3b(x - 2y) ← factor out (x - 2y) from each term

= (x - 2y)(2a + 3b)

Sophie says that if the interior angle of a triangle is 65 degrees and the exterior one is 295 degrees. Comment on her thinking
Yuri [45]
Sophie is correct because 295 + 65 = 360 and 360 is the # of degrees in a full circle
