Step-by-step explanation:

Given,

9 {x}^{2}  + 13x - 15

and

x = 2

Substitute x = 2 into expression.

9 {x}^{2}  + 13x - 15 = 9( {2}^{2} ) + 13(2) - 15 \\  = 9(4) + 26 - 15 \\  = 36 + 26 - 15 \\  = 62 - 15 \\  = 47

Please help me its a propotional question and answer of Z Y X
tino4ka555 [31]
Since the only two corresponding side you have are 10 units and 4 units, you can divide these two numbers to get the scale factor.

10÷4=2.5

next you find the sides corresponding to X Y and Z and if it is on the bigger figure you divide, if it is on the smaller side you multiply

X corresponds with 5 (so ×2.5)
Y corresponds with 8 (÷2.5)
Z corresponds with 10 (÷2.5)

final answer is X=12.5 Y=3.2 Z=4

I try to explain the question and give the answer, I hope this helps!

Answer with steps please i have 1 mark on this with steps
Aleks04 [339]

Answer:

56cm²

Explanation:

the amount of material he needs would be the total surface area of the box. surface area can be calculated by finding the sum of surface area of all the sides of the box. since the opposite sides are equal, we can find the surface area of 3 different sides and then multiply it by 2.

(4 + 4) + (4 + 6) + (6 + 4) × 2

= 8 + 10 + 10 × 2

= 28 × 2

= <u>56cm²</u>

i hope this helps! :D
