Answer:

No because the 2 is outside of the parentheses meaning it should be 9^2

Answer:

No, I will not simplify 3² first.

Rather I would simplify (12-3) first, i.e., 9.

Then simplify 9² which gives the answer 81.

Step-by-step explanation:

(12-3)²
= 9²
= 81

Make q the subject of the formula 5(q+p)=4+8

siniylev [52]

Answer:

q = $\frac{4+3p}{5}$

Step-by-step explanation:

Given

5(q + p) = 4 + 8p ← distribute the left side

5q + 5p = 4 + 8p ( subtract 5p from both sides )

5q = 4 + 3p ( divide both sides by 5 )

q = $\frac{4+3p}{5}$

(a)

A right angle sums to 90

6x + 4x + 10 = 90

10 x = 80

x = 8

(b) straight line = 180

5x + 13 + 3x + 7 = 180

x = 20

(c) Sum of triangle angles = 180

3x + 5 + 2x + 18 + 2x + 17 = 180

x = 20

(d) Sum of two angles in right angle = 90

90 = x + 30

x = 60
