Answer:

14.  27

16.  170

Step-by-step explanation:

We must follow Order of Operations rules here.  Work inside parentheses must be done first, then exponentiation, then multiplication and division, and finally addition and subtraction.

((5·7) - (8·4))³ becomes (35 - 32)³, or 3³, or 27.

16.  7² + ((46 - 7·2) + 2³)² becomes 7² + ((46 - 49) + 8)²

Again, do the work inside parentheses first:

7² + (3 + 8)² becomes 49 + 11², or 49 + 121, or, finally, 170

Use desmos graphing calculator, for visuals. It's easy to use as well.

A is 0 (zero)

(1x1 + 2x1 - 3)

B) D ( lies on 1 on our x-axis)

C) This tells you to draw a line at zero on the y-axis, a horizontal line BTW & read off the x values, where the line touches the pink graph/diagram.

y=x^2+2x-3 is the similar to x^2+2x-3=0 because the letter y now represents zero. So, that's why we draw the line y=0 (a horizontal line at zero). Then, use it to find the x values.

Thus, x = - 3 & x = 1

Hope this helps!

Answer:

30 short cakes

Step-by-step explanation:

25ml = 10ml + 10ml +5ml

each 10ml of milk can make us 12 short cakes

we can two 10ml of milk (20ml) which can make us 24 short cakes.

but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?

5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.

25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
