Answer:

Step-by-step explanation:

Let's use the rule GEMDAS (Grouping, Exponents, Multiply, Divide, Add, Subtract) from left to right. Therefore, we will simplify the equation in the parentheses. $2^{3} = 8. (1-8= -7)$ . -(-7) creates a double negative, deeming the 7 positive, because when there is two negatives the number will turn into a positive. $7^{2}$ = 49, -3 x 4= -12. Therefore the final form of the equation will be 49 - 12 = 37.

Let me know if there are mistakes.

Measure (7x+1) (2x+1)

Gemiola [76]

Smaller angle = 41°

Larger angle = 139°

Step-by-step explanation:

(7x - 1) + (2x + 1) = 180

7x + 2x - 1 + 1 = 180

9x = 180

x = 20

The measure of the smaller angle is

2x + 1

= 2(20) + 1

= 40 + 1

<u>= 41°</u>

The measure of the larger angle is

7x - 1

= 7(20) - 1

= 140 - 1

<u>= 139°</u>

The figures in the picture are similar to each other find the value of x

alisha [4.7K]

Answer:

x = 7

Step-by-step explanation:

Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':

$\frac{small}{large}=\frac{3}{6}=\frac{(x-3)}{(x+1)}$

Cross-multiply: 3(x + 1) = 6(x - 3)

Distribute: 3x + 3 = 6x - 18

Combine like terms: 21 = 3x

Solve for 'x': x = 7
