You just need to multiply the length with the ratio

for example, if the ratio is :2w : 3L , the actual width would be 2/3 x 27

= 18 cm

Write the given trinomial if possible as a square of a binomial or as an expression opposite to a square of a binomial: 15ab-9a^

MrMuchimi

Answer:

$- \bigg(3a - \frac{5}{2} b) \bigg)^{2}$

Step-by-step explanation:

$15ab-9a^2-6 \frac{1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{6 \times 4 + 1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{24+ 1}{4} b^2 \\ \\ = 15ab-(3a)^2-\frac{25}{4} b^2 \\ \\ = 15ab- (3a)^2- \bigg(\frac{5}{2} b \bigg)^2 \\ \\ = - \{ - 15ab + (3a)^2 + \bigg(\frac{5}{2} b \bigg)^2 \} \\ \\ = - \{ (3a)^2 + \bigg(\frac{5}{2} b \bigg)^2 - 15ab \} \\ \\ = - \bigg(3a - \frac{5}{2} b \bigg)^{2}$

The sum of the measures of two of the angles formed by the intersection of two lines is 114°. Find the measures of all angles. I

JulijaS [17]

Answer:

Measures of all angles are 57°, 57°, 123°, 123°

Step-by-step explanation:

Given:

Sum of two angles = 114°

Find:

Measures of all angles

Computation:

Sum of all 4 angles = 360°

Sum of remain 2 angles = 360° - 114°

Sum of remain 2 angles = 246°

So, first two angles = 114° / 2 = 57°

Second two angles = 246° / 2 = 123°

So, measures of all angles are 57°, 57°, 123°, 123°
